What an Electrical Engineering Degree Actually Teaches You

At its core, an electrical engineering program trains you to understand, design, and troubleshoot systems that run on electricity — from a simple household circuit to complex industrial power grids.

You will study topics like circuit theory, electromagnetism, signal processing, digital logic, and control systems.

The degree also builds strong foundations in math and physics — areas that many people overlook when they start but quickly realize are the backbone of everything in EE.

On the applied side, you learn to work with components like resistors, capacitors, op-amps, transistors, and microcontrollers — the building blocks of almost every electronic device you use daily.

And if you are curious about a specific area, like power electronics for renewable energy or embedded systems for IoT devices, the degree gives you a structured roadmap to specialize.

Best Free Electrical Engineering Courses by Topic

To make the most of your self-study, it helps to organize your learning by topic rather than jumping between platforms randomly.

Here is a breakdown of the best free resources for each core area of an electrical engineering online courses curriculum:

Core Circuit Theory and Electronics

MIT OCW – Circuits and Electronics (6.002): The quintessential starting point. It covers voltage, current, energy storage, and amplifier design at a university level.
Introduction to Electronics (Georgia Tech on Coursera): Excellent for understanding semiconductors, diodes, and op-amps — audit it for free.
Khan Academy – Electrical Engineering Section: Great for beginners. Covers the basics of voltage, current, and Kirchhoff’s Laws in a clear, step-by-step format.

Math and Physics You Cannot Skip

Electrical engineering is deeply math-heavy, and skipping this foundation means you will struggle with almost everything else.

Khan Academy – Multivariable Calculus and Differential Equations: Essential for circuit analysis and electromagnetism.
Walter Lewin’s Physics Lectures (MIT OCW / YouTube): Legendary for a reason — these lectures make electricity and magnetism genuinely visual and intuitive.

Just like someone going into an automotive technician training program needs solid diagnostics knowledge before touching an engine, EE students need math fluency before tackling advanced circuits.

Power Systems and Energy

Electric Power Systems (University at Buffalo on edX): Ideal if you are interested in grids, transformers, and energy generation — audit it free.
Introduction to Power Electronics (UC Boulder on Coursera): Critical content for anyone targeting EV technology, solar inverters, or renewable energy careers.

If the energy sector interests you, it is worth knowing that certifications like HVAC certification online are closely related to electrical systems — and many professionals pursue both to expand their career options.

Visual Learning and YouTube Channels Worth Bookmarking

Sometimes a five-minute animation explains a concept better than a sixty-minute lecture — and the EE community on YouTube is one of the best educational resources online.

Here are the channels most recommended by engineering students and educators:

Channel / Platform	Best For
The Engineering Mindset	Exceptional animations of 3-phase power, motors, and transformers
ElectroBOOM	Learning “what not to do” through humorous but technically sound experiments
GreatScott!	Practical DIY projects bridging theory and real hardware
Digi-Key / Adafruit	High-quality tutorials on components and microcontrollers (Arduino/ESP32)
Ben Eater (YouTube)	Building an 8-bit computer from scratch — a masterclass in digital logic and computer engineering

These channels work particularly well alongside structured electrical engineering online courses, giving you the visual context that textbooks and lectures sometimes miss.

Complete Enrollment Process for Free Electrical Engineering Courses

Enrolling in a free electrical engineering online course is simpler than most people expect — and you can get started today, without a credit card or application form.

Each platform works a little differently, so here is a step-by-step guide for the three main ones you should know.

How to Access MIT OpenCourseWare (OCW)

Go to ocw.mit.edu and use the search bar to find the course you want — start with Circuits and Electronics (6.002) or Signals and Systems (6.003).
Click on the course title to open the full course page.
No account or registration is required — all materials are publicly available.
Navigate through the tabs: Lecture Notes, Assignments, Exams, and Video Lectures (when available).
Download the materials you want or study directly in your browser at your own pace.

MIT OCW does not issue certificates, but it gives you direct access to the same content MIT campus students use — which is the real value here.

How to Audit a Course on Coursera for Free

Go to coursera.org and search for the course you want — for example, Introduction to Electronics by Georgia Tech or the Embedded Systems Specialization from UC Boulder.
Click on the course and then click “Enroll for Free.”
On the next screen, look for the option that says “Audit the course” — it usually appears as a smaller link below the payment options.
Click it. You will get full access to video lectures and reading materials at no cost.
Note that graded assignments and the official certificate require payment — but the learning content is completely free.

If your goal is to show employers proof of completion, consider paying for the certificate on one or two flagship courses — it is a one-time cost that can strengthen your portfolio significantly.

How to Audit a Course on edX for Free

Go to edx.org and search for your target course — try Electric Power Systems from the University at Buffalo as a strong starting point.
Click the course and then click “Enroll.”
Create a free edX account if you do not have one — just an email and password.
After enrolling, select the “Audit this course” option when prompted.
You will have access to lectures and course materials for the duration of the course session.

Keep in mind that audit access on edX sometimes expires when the course session ends, so it is worth downloading or saving key materials as you go.

Can You Study Electrical Engineering Online for Free?

Yes — and the options available today are genuinely impressive, especially if you know where to look.

Platforms like MIT OpenCourseWare, Coursera, and edX give you access to university-grade content at zero cost, as long as you are willing to put in the work.

MIT OCW, for example, publishes the actual materials used in campus courses — including lecture notes, problem sets, and exams from programs like Circuits and Electronics (6.002) and Signals and Systems (6.003).

These are the same resources that MIT students use, and they cover the foundational topics of any serious electrical engineering online curriculum.

On Coursera and edX, you can audit courses from universities like Georgia Tech and UC Boulder without paying for a certificate — this gives you full access to video lectures and reading materials for free.

If you have ever looked into an electrician apprenticeship program, you already know how valuable hands-on electrical knowledge is in the job market — and online courses can complement that practical experience with strong theoretical grounding.

How to Choose Your Specialization Track

Once you have the fundamentals covered, narrowing your focus is one of the smartest career moves you can make in electrical engineering.

Here are the most in-demand specialization tracks and the best free resources for each:

Embedded Systems and Microcontrollers

This track is perfect if you want to work with IoT devices, robotics, or consumer electronics.

Look for the Embedded Systems Specialization from University of Colorado Boulder on Coursera — it covers sensors, actuators, real-time operating systems, and motor control.
Digi-Key’s tutorials on Arduino and ESP32 are excellent for hands-on practice alongside the theory.

Digital Logic and Computer Engineering

If you are leaning toward computer hardware, this is where to start.

Ben Eater’s YouTube series on building an 8-bit computer from scratch is widely considered one of the best free resources in this area.
It bridges digital logic, memory design, and instruction sets in a way that is both practical and deeply educational.

Power Electronics and Renewable Energy

One of the fastest-growing areas in engineering, driven by the global push toward clean energy.

Introduction to Power Electronics (UC Boulder on Coursera) is critical for EV technology, solar energy systems, and industrial power conversion.
Pair it with the Electric Power Systems course from University at Buffalo to get a complete picture of how energy is generated, transmitted, and used.

This kind of structured specialization is similar to what you find in programs like a welding certification course or a construction management certificate online — focused, practical, and directly tied to career outcomes.

How to Turn Your Free Electrical Engineering Studies Into Career Opportunities

One of the most common questions people ask is: will employers take my self-taught electrical engineering background seriously?

The honest answer is — it depends on how you present it.

Employers in tech and engineering increasingly value demonstrated skills over credentials alone, especially for roles in embedded systems, hardware development, and power electronics.

Here is how to make your self-study count:

Build a project portfolio. Document every circuit design, simulation, or code project on GitHub or a personal website. Show that you can build real things, not just watch lectures.
Earn verifiable certificates. Even when auditing courses for free, consider paying for the certificate on at least one or two flagship courses from Georgia Tech or UC Boulder — these carry real weight with employers.
Combine online learning with practical experience. Look into lab kits, Arduino projects, or local maker spaces where you can build and test physical circuits. Hands-on experience is irreplaceable.
Network within engineering communities. Forums like Reddit’s r/ElectricalEngineering or professional groups on LinkedIn can connect you with practitioners who hire, mentor, and share opportunities.
Target entry-level roles strategically. Positions like electronics technician, PCB design assistant, or junior embedded systems developer are realistic entry points for self-taught candidates with strong portfolios.

If you are also exploring other technical career paths, it is worth looking at what programs like free job training resources or a medical billing and coding certification offer — sometimes combining technical and administrative credentials creates unique career advantages.

Is a Free Online Electrical Engineering Degree Enough to Get Hired?

This is the real question — and the answer is more nuanced than a simple yes or no.

For roles that legally require a licensed Professional Engineer (PE), you will need a formal accredited degree from a recognized institution.

However, for a wide and growing range of engineering-adjacent roles — including hardware engineering, firmware development, power systems analysis, and technical sales — a strong portfolio built through online electrical engineering courses combined with practical projects can be genuinely competitive.

Many hiring managers in the tech industry care far more about what you can build and what problems you can solve than which university issued your diploma.

That said, if your goal is to become a licensed electrical engineer, the free online path works best as a foundation — one that helps you understand the material deeply before pursuing a formal electrical engineering program through an accredited institution.

Think of the free resources not as a replacement for a degree, but as the smartest, most cost-effective way to build the knowledge base that makes everything else easier — from college coursework to technical interviews to on-the-job problem solving.
