Mechanical Vs. Electrical Engineering: How to Pick the Right Major

A common toss up for students is whether to major in mechanical or electrical engineering These are two of the most popular engineering majors so I wanted to address this for anyone’s who on the fence Now of course there’s no right answer for these two, and I’m not gonna give an answer really These majors both have huge job opportunities in lots of sectors and have high salaries I’m just going to explain the similarities and differences in the curriculum and careers so you can make a more educated decision for yourself Now to start off simple, if you’ve taken physics in high school, think of what you enjoyed more The circuits part or the mechanics part, like projectile motion, forces, energy, momentum, etc I know you only got a small glimpse of everything, and this won’t be a deciding factor but could at least point you in the right direction of electrical or mechanical engineering respectively Now when it comes to the curriculum, let’s just put it simply, what interests you more? Circuits and electronics, signals, some programming, and yes this would your first actual program you make and electromagnetic waves or, are you going enjoy analyzing complicated forces in various systems, fluid dynamics whether it be water or air and heat transfer and thermodynamics As you can see the curriculum for both these majors is very different but there are some similarities that I will explain soon In a previous video I talked about why electrical engineering is a difficult major. To summarize, electrical engineering is a little more “magical” As in when you get that antenna sending wireless signals, or the circuit lighting up an LED, or whatever you have you can’t physically see how it’s happening You can’t see electrons moving through wires, or wireless signals moving through air You have to understand the equipment used to detect everything and the physics behind what is going on fundamentally This isn’t as true with mechanical engineering cause especially in undergrad You’ll analyze fluid moving through a pipe or an engine, or the forces and motion on a complex system You can often visualize these more, and see them work So now for those who are curious about “How much math will use in these two majors?” They are very similar and they both use more than most other engineering disciplines And do expect to see calculus level math Mechanical engineers use calculus to analyze the vibrations of a system using differential equations to analyze complex heat flow, Or something just like a rotating object often involves calculus to solve for how it will rotate given some torque Those values you see indicate basically how hard it is to rotate the object about some point whether it be it’s center, or end. This is called inertia and it’s equation looks like this. Electrical engineers use calculus to prove how current will move through a circuit with inductors, capacitors, and resistors (not shown here) They use it when analyzing AM and FM radio signals They use it when analyzing electromagnetic waves in general and how they are created from something like current in a wire Again, you may have seen something like this in high school physics already but probably without calculus unless you took AP physics C So if you love math then that’s good news cause both of these have a lot and you’ll see way more beyond calculus AB and BC And if you choose electrical and really enjoy high level math then I can say that RF might be the best concentration for you RF stands for radio frequency, and is essentially the wireless communications concentration of electrical engineering Those students learn more about wireless systems, antennas, and so on and those classes will be very math and calculus intensive If you’re not so much interested in high level math, then I can say that not every class you take will involve calculus for either of these majors But just be warned that it will come up and you should enjoy it somewhat before entering either of these two majors Now, mechanical engineers do take some circuits and electronics classes whereas electrical engineers don’t take any mechanical engineering classes, so keep that in mind Honestly, a lot of mechanical engineers don’t enjoy their circuits classes cause it’s not what their interested in but as a mechanical engineer you will take about two classes on circuits and electronics which surprisingly covers around four electrical engineering classes It’s just condensed and simplified for the mechanical engineers They go through it faster, but in less depth Then this leads to the fact that mechanical engineers can concentrate in mechatronics This is where mechanical engineering meets electrical and computer engineering If you choose this you will learn more about programming and circuiting so you can work on things like robotics Instead of just being able to make something structurally You will have the skills to build it, circuit it, and program it to maybe detect and avoid obstacles or whatever your project would be. Knowing this, if someone came up to me and said “I like mechanical and electrical engineering the exact same, tell me what to choose.” I would probably say, go with mechanical engineering, and concentrate in mechatronics You’ll be exposed more to both fields than you would as an electrical engineer You’ll have a great background for the job market and maybe if you pursued a master’s degree, you’d be able to make an easier decision since you have more exposure to both disciplines Again, there’s no right answer, but all things equal and I had to pick, that’s what I would say. Now let’s move on to careers A question I hear often is, “If I want to work on (blank), should I major in electrical or mechanical engineering?” and sometimes that’s a valid question, but other times not so much For example, someone says “I want to work on alternative energy, should I pick mechanical or electrical?” Well guess what, you’ll see both those majors all over companies that work on alternative energy So let’s say you want to work on wind energy, well which part? Do you want to work on generating and delivering large amounts of electrical power? Do you want to take classes in how high power systems work electric motors, generators, and so on? Or do you want to analyze maybe the structure of the wind turbine Like what shape will cause more rotation from the wind, where you need to understand fluid mechanics in terms of air. Or maybe you want to help with the manufacturing of the machinery that is used. Same thing applies for solar energy Do you want to work on the circuitry for the solar panels, and distributing the electrical power that’s created? Or do you want to work on designing and manufacturing the panels themselves? Or work on the lenses that track and focus the sunlight to maximize efficiency and so on Let’s say you want to work on satellites Well do you want to work on the satellite communication? Or the sensors on board that take measurements? or maybe a remote sensing system that’s on the satellite? That’s all electrical. Or do you want to analyze the temperature changes during orbit or the vibrations that occur to ensure nothing is damaged Even something down to the Gimbal that turns the antenna needs mechanical engineers. When an antenna needs to track another, it uses a Gimbal that often has three axes of rotation You’d mount an antenna on it, so it could turn to communicate with the receiver If the receiver is in line, then everything’s fine But if during orbit they move out of line with each other, the gimbal would turn the antenna as needed An electrical engineer could analyze the signals that tell the gimbal how much to move and the mechanical engineer implements the gimbal to actually move as accurately and efficiently as possible Maybe you want to work on the new electric cars that have autopilot Electrical engineers might implement sensors, and the programming that instructs the vehicle to move based on the sensors reading’s They could work on any high power circuitry and electronics that the vehicle uses Whereas mechanical engineers could work on the motors the design and structure of the car for safety or even aerodynamics and also the manufacturing of the car parts themselves. Go ahead and look up “electric vehicle projects” at colleges and you’ll see almost exclusively electrical and mechanical engineering students working on these Maybe you want to work on prosthetic body parts for people Well do you want to analyze the electric signals coming from people’s muscles And use that, along with some programming, to tell the prosthetic arm to grab something for example. Or do you want to make sure the prosthetic limb can supply the right amount of force to pick up that object or can withstand a certain amount of force without breaking and is light enough to not cause stress on the person’s body This is what biomedical engineers might be passionate about working on But you’ll see electrical and mechanical engineers all over these projects as well Even something like working on printers needs both disciplines Printers receive lots of signals and use many electronic components to make it work which is where electrical engineers come in But remember in an inkjet printer there are moving parts that need to be extremely accurate to place the ink Mechanical engineers are needed for that This applies to 3D printing as well Where there needs to be extremely precise placements, especially when we are 3D printing stuff like organs now mechanical engineers would help design these systems There’s rockets, aircrafts, robotics, and I could go on for a while so many things need electrical and mechanical engineers It’s actually less common to see just one discipline working on a big project For these two majors it’s not so much which major is better to work in some sector it’s a matter of what you’ll enjoy more What do you have more interest in learning and understanding when it comes to the projects I’ve shown you Now of course there are things that do involve just one major or the other, but usually on a more zoomed in scale Like if you wanted to improve the efficiency of the internal combustion engine, you wouldn’t go into electrical engineering But if we zoom out to just cars in general, then again you could go into either major at least now with electric cars becoming more popular It’s going to help to know which sector you want to go into whether it be biomedical, aerospace, automotive, etc but also specifically what part of the projects you’d be more interested in working on Remember this will be your life almost everyday, make sure you are going to enjoy going through the actual process of making these designs come to life Put yourself in the shoes of these people and think “What will I like doing more?” Now this video was focused on electrical and mechanical engineering but just note many more engineering disciplines are needed for all the projects and careers I’ve talked about So many things are multidisciplinary now But when it comes to these two majors which have so many positive aspects, it comes down to what you’ll enjoy doing more Remember to like and subscribe, and if you’re still having trouble deciding, check us out at, and good luck on your search.

  1. In this video I say that mechanical engineers take some electrical classes but electrical engineers don't take any mechanical engineering classes. As some comments have pointed out this does depend on your university (and sometimes your concentration) so there's no guarantee on what you can expect. Some electrical engineers might take thermodynamics, mechanics of materials, and so on, just be sure to look into what colleges you apply to. Sorry for the confusion!

  2. so say i want a leg into engineering.. use a cert 2 to step up to university..

    im mechanically minded but understand the relationship between moving parts and electrical signals activating these.

    like electronics but love mechanics.

    mechatronics.. how do i get there? i think is what I'm asking

  3. I wish I didn't have to go through statics and material strength as an electrical engineering student in Poland. It was kind of simplified for my course, but still really annoying and i failed it many times

  4. Do you like smaller classes filled with people equally as confused as yourself? Electrical

    Do you like large classes filled with people that know all the material better then you ever will? Mechanical

    So I did EE, and my friend did Mechanical, here is what it boiled down to at our school. Electrical had tiny classes (My largest electrical class was about 30 students) which was excellent for learning the material and getting help from the prof, but the material was always at an extreme; when it was fun, it was like a pornstar orgy with non-stop orgasms, but when it was hell, it was like the Devil's anus the day after a Taco Bell bender. Besides having your GPA drop too much and have the school kick you out, there was really no pressure if you had a bad class or even flunked some; C's get degrees. As for mechanical the classes were enormous (150+ students) so you couldn't really expect the prof to ever know who you were or be able to help you. The material was easier, its was pretty fun most of the time, but there was still stuff that was tough and boring, but not at the extremes like Electrical was. It was easier to keep your grade up but it was tough because you HAD to keep your grade up, if you fell below I think a 3.8 GPA, you didn't have a spot anymore. Electrical is not something most people understand or can learn very well, Mechanical on the other hand is and way more people try to go into it and they always have way more Mechanical students then seats in classes so its a fight. Electrical on the other hand they usually couldn't quite fill all the spots in any class any year.

  5. At the end of the day..those welding or coating inspector get paid more..speaking from is not fair lol..

  6. I have been watching your channel for quite a while, all I can say is that you have one of the best Engineering channels and your content is very beneficial. I noticed you don’t talk much about Chemical Engineering and as a fresh man in Chemical Engineering I would like to hear more about it in a later video of yours. Great work all in all, keep it up!

  7. I'm doing mechanical and automation and I'm screwed from both ends……equally.
    odd semesters are mechanical intensive.
    even semesters are electronics and electrical intensive.

    programming is a cherry on top: C, assembly and python.

  8. Where do electrical design for construction industry goes? 😕 Electrical are essential in every construction too. And EE are making a lot of money in to this

  9. Well I would also add, Embedded SW and software engineering, bringing machines to life and to think to what they are commanded to do…….I worked at SIEMENS: you can see clearly that the future is man and the machine…….SW-HW-ME one cannot go without another…..HW and PCB and electronics connect mechanical and software engineers, without HW there is no connection…..

  10. dont give a crap about.salary. Could easily make 100k a year with stocks and real estate/selling planes. Just a want a side career i love

  11. Don't worry, no matter which Engineering discipline you choose, there will be a lack of girls in both,
    so you don't have to worry about not having girls in your class rooms, because the other Engineers are going through the same struggle.

  12. I'm already working in the field I want. I work as an electrical designer in the AEC/MEP industry and I don't have a degree. A pure electrical engineering degree I don't think will work for me. I saw some schools that had Engineering Technology: Power Systems programs. Unfortunately, it's not about what school to go to right now, it's about if I have time to go to school again and handle school at the same time. The answer is no btw. I'm learning a lot at my job though but the engineering fundamentals I don't know. And forget about getting a PE. That's 20 years from now. Literally & unfortunately!

  13. I'm already doing masters on mechanical, but still watching these vids 😀 Really nice and compact video. Both majors are so broad that in that sense they are very nice picks to study.

  14. I’m gonna be a math major but mechatronics sounds really interesting, hopefully I can get a class in that field

  15. It's like mechanical job is heavier than electrical which is my common sense reply me if I'm wrong

  16. I’ve worked in solar for almost 10 years but I want to go back to school to finish a degree and go on to my masters. With my solar background, which would be better? Or possibly Civil. I could see a benefit in all

  17. I want to become an artisan in creating electronic devices, such as cameras, what major and minor should I consider taking in engineering? Would Electrical Engineering be a good major ?

  18. Is there an Electronic Major in EU? in México electrical engineering and electronic engineering are so different mainly because in Electronics are more focused in circuits involving semi conductors while electrical is more about more industrial electrical systems like for power plants

  19. Majorprep ,plz say that which one is to study electrical engineering or mechanical engineering in diploma

  20. Great video. What you're saying makes perfect sense. I've been seeing more and more degrees in Electronics Engineering. What's the difference between Electrical Eng and Electronics Eng?

  21. A big thank you! I hesitated between these 2 majors and this video helps me to make my choice! I subscribe and wish you a great day!

  22. For example If I wanted to major in mechatronics engineering and I go to CSUN. They don’t offer that major, but they offer electrical engineering. Would I still be able to major in mechatronics engineering at CSUN if I apply with an electrical engineering major?

  23. This was extremely helpful. So thank you! I'm from Spain, where if you want to get to university/college (I don't know the difference), you have to got through some tests (I think pretty much like the SATs maybe?), and (in general) if your grade is higher than a certain grade the degree has that year, you go in. So I thought I'd like to go into mechanical engineering, but I didn't get the grade. One option was to wait for the next year's tests and try to improve the grade, but I'd waste a whole year. So with the grade I had, I coul enter electrical engineering, and as the classes in the first year are exactly the same as in mechanical engineering, I could change to ME in the second year. So I saw EE always as a bridge to ME. But after this video I'm not so sure anymore if electrical is gonna be the bridge or the degree I want to take. So this video helped me because maybe I'm better in EE and I almost made a mistake… Have to research more and think about it more though. After all, it's my future I'm talking about. So thank you!!

  24. Computer science and electrical engineering student here, it's not how you think it is, or how people tell you it is.

  25. Hello Sir! I've got admission in Computers Engineering, Telecommunications Engineering, Civil Engineering, Materials Engineering, Chemical Engineering and CS for Undergraduate Degree in NUST.
    What should i choose? Kindly guide me. I'll be waiting for your reply.
    Thank you for your time.
    Regards: Taimoor Hassan.

  26. I have been looking for future education possibilities in Universities in Finland, and I am interested in Energy Engineering (in Lappeenranta University of Technology) and your channel didn't have a video about it. I kindly request that if you have time, could you make one of Energy Engineering? I've already looked into the website of the Uni, but you tell things differently so that is why I'd like to see such a video on this channel. I please.

    Oh, and while writing this I came into a question I wanted to ask: what engineering field could be suitable for EnE as a minor?

  27. this video made me feel so better because from past 2 days i was F***ing my mind up thinking that i made the wrong decision now im gonna grind my whole life, there is no more purpose in my life , I should Die now but man you got my back
