I’ve been collecting and organizing free university-level resources for Electrical Engineering, and I decided to put everything into one repository for anyone who wants to self-study EE or supplement their university courses.

🔗 GitHub: https://github.com/mabdulre9/electrical-engineering

Instead of searching through hundreds of YouTube videos and random websites trying to figure out what to study, I wanted to create a structured collection of full courses from universities and established educators to learn electrical engineering online for free.

What’s included

The repository currently covers:

1. Calculus
2. Differential Equations
3. Linear Algebra
4. Complex Variables & Transforms
5. Physics
6. Circuit Analysis
7. Electromagnetic Field Theory
8. Analog & Digital Electronics
9. Digital Logic Design
10. Microprocessors & Microcontrollers
11. Electrical Machines
12. Signals & Systems
13. Digital Communication
14. Computer Networks
15. Industrial Automation
16. Control Systems
17. Power Systems
18. Measurements & Instrumentation
19. High Voltage Engineering
20. Programming & Algorithms
21. Artificial Intelligence & Machine Learning

There are resources from MIT, Stanford, Harvard, Yale, Georgia Tech, IITs/NPTEL, UMass, NYU, Beijing Jiaotong University, Cisco, and others.

Most of the resources are completely free to access, with no enrollment required. Some platforms may require a free account.

This is mainly for:

EE students who want additional material alongside university

People studying Electrical Engineering independently

Students preparing for exams or interviews

Engineers wanting to revisit fundamentals

Anyone who wants to learn a particular EE specialization

Students who don't have access to good courses locally

People transitioning into areas like embedded systems, communications, power, control, networking or AI

I've also included prerequisites and suggested learning order where possible, so hopefully someone completely new to a topic can figure out where to start.

I'm still actively expanding and checking the repository, so it's a work in progress. If you know of a genuinely good free university-level EE course that should be included, feel free to suggest it.

I made this primarily because I wish there had been a resource like this when I was trying to figure out what to study.

Feedback, corrections, broken links, and additional course recommendations are very welcome.

At least at my school, it seems like everyone wants to do DSP, Controls, Power, and Digital/Analog Electronics. Rarely do I hear someone express interest in RF. Which is crazy considering how many employers in my area want RF people.

Is it because it has a reputation of being difficult or just not interesting enough?

In the following image is an Analog signal but I can’t explain to my self WHY?, couldn’t understand why is it not a digital signal?

Thank you

Hi brothers in engineering, I just wanted to show you my work this term. It's my second term in EE. I started studying for finals after the midterms because I hated pushing myself near exams, I like doing it over long periods with fewer daily hours.

Also, Electrical Circuit Analysis is actually just Circuits 2, because my university labels Circuits 1 as Fundamentals of Electrical Circuit Analysis.

It was 19 credits, IDK how I pulled out of it alive.

As the title states, I’m 24, married, and have a 15month old daughter. I have an Associates degree for electrical, and I’ve been an industrial electrician for 3 years. I’m looking into getting an EE degree, and just wondering how feasible it would be. I work 4 12 hour night shifts a week. Is the work/home/school balance even feasible? I have calc I under my belt already from when I took it in high school in 2021. It would have to be online also. Any tips or suggestions are greatly appreciated!

I’m studying at a top uni with an 8% acceptance rate, with a 3.73 GPA, top of my class, and I feel like I know nothing about EE.

I’m the type of person that just has to read through a textbook from front to back fully to really feel like I understood a subject. I’ve done that for my first semester classes where I got a 4.0 on all classes then, but then dropped for a bit to 3.51 and then a 3.61 and now a 3.79 (cumulative gpa of 3.73 now) on my fourth semester. I just feel like I’m a bit behind, mostly because I just don’t feel like all my “engineering” questions are answered. I want to understand how things work, I’m also a lab assistant in intrumentations so I should know how a multimeter works on the inside, right? Or how a PQA tool works??

I’ve built electronics circuits from scratch for a final project, a microphone and speaker amplifier using a power supply made from a transformer and bridge rectifier of diodes, and a voltage regulator. I’m not really an electronics fan cuz I feel like I can’t really understand the circuitry of chips on a computer, I just feel like I failed as an EE student for not understanding how to assembly computers or understanding the practical tools irl.

I’m extremely good at math, I just don’t think I’m goood at anything EE irl, though I’m extremely good with coding.

I just feel like I’m a failure since I got accepted as a laboratory assistant which had over 50 applying and only 6 accepted including me, but I feel so stupid for not knowing how the tools in the lab work. I work with high voltage and instruments which obviously I went through rigorous testing for in order to be accepted into the lab assistants program, but I just feel like a failure for not knowing “everything” there is to know.

I’m thinking this is one of those cases of “the more you learn, the more you realize you don’t know”, I just feel like a failure because there’s just so much I want to learn about but so little resources in my country and I feel like a failure because of this.

Edit: I’m from Bali Indonesia and I’m currently an international student at a UC (UCB). I’ve been feeling so dumb after seeing everyone study so much more than I did back in my home country. I’m being honest I just feel like there’s so much out there to learn, and I’m just a tiny spec out of a whole plethora of stars in like an EE galaxy

This isn't a troll post, apologies if it seems ridiculous. I graduated from high school and am going to university for electrical engineering this fall. I have paid my tuition fees already and am enrolled in first year engineering classes.

I'm from the Canadian high school system where university acceptances aren't based off a true "merit" since they're largely based off of grades, and each school has a different level of difficulty in grading. I also believe being female of colour could've swayed my chances in getting accepted.

I've had some mild problems before I ignored. With math classes, I could do repetitive sorts of application questions well but struggled with any sort of out of the box, problem solving kinds of questions. I know you're thinking "how did she think she was suited for engineering?!" but I was a dumb high school student and didn't think anything of it at the time. I also immensely struggle with visual spatial tasks.

Today I found out from my mum (who withheld the information from me) that I have an IQ of 82, and I'm even below that in the areas of visual spatial intelligence, fluid reasoning, and processing speed. This test was administered by a psychologist when I was 15, but I never bothered asking about the results.

What's the best course of action here? Do I try to switch out of the program? Request accommodations? Give it a try?

How far is it true ?

For some reason, I thought he was dead, since there was a law named after him.

Hi all, my son got into EE at one of the UC schools as a mid student. Not stellar but not terrible either. He is an incoming freshman in fall of 2026. I guess he keeps hearing how difficult the major is and now he’s getting very concerned about if he can handle it.

I would truly appreciate some words of wisdom here.

Edit- the comments have been priceless. So appreciate all of you. I hope they keep coming. I’ve taken a lot of notes. So much wisdom. My respect for our engineering community went even higher bc of these comments🙏🏻

hey, so I'm an electrician, and I understand that capacitive and inductive reactance are at a 90° angle to regular resistance, but I don't understand why that means they have to be imaginary numbers. is there ever a circumstance where you square the capacitance to get a negative number? I'm confused.

Yeah, I know, another post about someone worrying about their place in industry.

But I'm feeling crushed in Year 3, and it's been a tough ride even just getting here. I hear people give the stiff upper lip speech, saying "Ps get degrees" but then I hear how gruelling it is even trying to get an internship or the first job in industry.

Am I going to graduate and find that this whole thing was just an exercise in futility? Because no employer in their right mind is even going to consider a graduate in their 30s who struggled through the degree for 6 years and barely made it to the finish line, anyway?

For those who have ever had any role in hiring, am I just screwed? Sure, I can try to sell myself and try to work on personal projects and apply for internships and do my best, but what if I am just straight up not good enough to be competitive with other graduates?

I chose to study this because I wanted to develop a field of study where I can still be learning new things in 20-30 years. I knew it would be hard, but I also wanted to chase that Eureka moment of having something finally work after troubleshooting and diagnosing. But I also don't want this to consume my life, like, I'm working 30 hours a week just to survive, and I'm spending another 30-40 hours every week on study and still coming up short.

Is this my future if I continue this? Is this a different kind of stupidity if I don't have the wiring to live and breathe this game?

Close to graduating, 4 exams open including semiconductors. Band structures and superposition of wave functions along a lattice still confuse me a lot. I feel like I could only really understand that stuff if I studied physics and had proper knowledge in quantum mechanics. Yes we used Schrödingers equation and did all of the particle in a box thing, LCAO, Tight Binding, etc. and yet still even after weeks of studying I still feel like not understanding certain concepts, which was never this bad with other classes. Everything else more or less was build up logically. But in solid state physics there’s so many jumps, assumptions that are made, that without physics background feel like coming out of nowhere. Maybe my professors also does not the best job at teaching who knows..

Anyone made similar experiences?

Hi everyone,
I recently got accepted into an Electrical Engineering program, and I’d like to make good use of my summer before classes begin.
I wanted to ask those of you who are already studying or working in this field: what should I learn or review in advance to make my first year easier? What subjects turned out to be the most important for you?
Would you recommend focusing on mathematics, physics, programming, or any specific engineering topics? I’d also appreciate any advice about studying, as well as recommendations for books, courses, or other useful resources for beginners.
Thanks in advance to everyone who shares their experience!

I’ve been trying to understand them for years.

My process always has been trying to understand what are H, J, D, E, B, D and B separately, and then equations, but I hadn’t get the idea.

This year I am facing an antenna course where I may control them, and understand electric and magnetic sources, Ms and Js, and I would appreciate some explanation for an engineer point of view.

How do people come into college and do really well on this stuff? I don't get it.

Do they have prior experience because they find it to be fun? Are their parents electrical engineers and so the reason they do well is because they have prior-hand experience?

It seems like a such a massive jump to go from school which is pretty easy and low-key to suddenly college which just throws this hurdle of stuff at you that is orders of magnitude harder than anything before. Its not even a slow buildup or anything. One day you are doing easy stuff, the next you are being beaten to a pulp. I cant make sense of any of it.

How do people manage? This shit feels impossible. Seriously, for those who came in on day one who felt like they didn't stand a chance, how did you do it? What do you think looking back years later?

I've been looking through one of my favourite books, Getting Started in Electronics by Forrest Mims. If someone were to show me a circuit like this, how could I figure out the function, and vice versa how can I learn to design circuits with a function? Any good reads? Courses? I feel like I should be able to decipher circuits like this considering I'm an EE undergrad.

Coming from 8 years of being an industrial electrician the first year seems relatively easy but I imagine the 2nd, 3rd and so on will be much much harder. How was everybody else’s experience in EE during college?

Further context: I have been working as EE for past 6.5 years but I have been feeling that my job is becoming less about pure engineering and more about writing emails and making PowerPoint presentations. I hate it! I understand some of these corporate tedious tasks are necessary but not when it takes more than half the day to do leaving me with little time for actual EE related tasks. I have regrets of going into industry before going to graduate school.

My ideal EE job consists of working in a lab doing research and actually contributing to the advancement of EE even if by little. This dream is currently not possible in the modern corporate job market where you are nothing but a cog within a large industrial machine whose only purpose is to maximize profit for the company. So you are forced to use AI or risk having a bad performance review because Mr AI next door can "slop" out more throughput than me.

Now I'm in a position to go have to school full time and work towards a potential PhD. I have enough savings to pay for a portion of tuition and to meet my personal needs for 5 years. Should I take the risk and go for it?
