Course Description

"Ultimate Electric Circuits Course from A to Z for Beginners"

This is the only course with everything you need to know about the basics of electric circuits for complete beginners without any previous knowledge.


This course starts with the basic concepts of electricity, to the level where you will be very familiar with circuits. Throughout the course, you will get:


  • Basic concepts of electric circuits: This will help you understand the very basic definitions of electricity, including voltage, current, power, and more.

  • Basic laws of electric circuits: This part will teach you about the branches, nodes, KVL, KCL, Ohm's law, and Delta-Wye transformations.

  • Methods of analysis: You will learn how to analyze electric circuits using nodal analysis and mesh analysis.

  • Circuit theorems: In this part, you will learn more advanced circuit analysis techniques such as the superposition theorem, source transformation theorem, Thevenin theorem, Norton theorem, and maximum power transfer.

  • Operational amplifiers: You will be introduced to operational amplifiers, including inverting, non-inverting, summing, difference, and cascaded amplifiers. These amplifiers are helpful in inverting, amplifying, or adding or subtracting different input signals.

  • Capacitors and inductors: These components are important in the electrical system and other applications. You will find inductors as a representation of electrical machines and capacitors that can be used in power factor correction.

  • First-order RL, RC, and second-order RLC circuits: These circuits are composed of resistors and inductors or resistors and capacitors. We will understand how to analyze them in the free and forced responses.

  • Basics of AC circuits: AC power, or alternating power, is the one which we have in our homes. We will learn about them and what the difference is between them and AC circuits.

  • Analysis of AC circuits: In this part, we will start analyzing our AC circuits with the different theorems that were discussed at the beginning of the course.

  • Resonant circuits: In this part, we will discuss both series and parallel resonant circuits. These circuits have a crucial effect on electric circuits and have practical applications.

  • Electric circuit simulations using MATLAB: We will learn the simulation of many electric circuits in the well-known simulation program MATLAB Simulink. This will be a fun part that will increase your knowledge about electric circuits.


All of these topics are in step-by-step lessons with many solved examples.


Bonus Gift:


You will also find the slides for the Ultimate Electric Circuits Course Bundle for those who are interested in them or have them as a revision for themselves:


  • 497 Pages of Electric Circuits Course Slides

  • 95 Pages of Electrical Resonance Course Slides


Take this bundle if you've been looking for ONE COURSE BUNDLE with in-depth insight into the basics of electric circuits.

I like how the instructor explains items from multiple viewpoints to be sure I understand before continuing onward. He also does an excellent job of reminding me of basic calculus concepts as we progress.

By Jacques Nsangou on 4/18/2025

This was a great opportunity to update my knowledge on something I studied several years ago. I really enjoyed the course and the special emphasis the lecturer made on each key point. MATLAB was introduced at the end on assumption that the learner is MATLAB literate which frustrated me somehow. A precious resource indeed!

By Tony Mendizábal on 4/11/2025

Excelente, por sí solo el curso es muy bueno, sin embargo, recomiendo acomapañarlo con el libro mencionado en el curso para que la ruta de aprendizaje tenga más beneficios.

By Ted Olivarez on 11/12/2024

This is an excellent quick presentation in circuit analysis, I most impressed with the methods used to solve the example problems. These are good examples and the solutions are very well explained. The only negative of the course is the translation of his talk, many words are translated wrong. But overall a highly recommended course.

By Tobias Jacobsen on 8/20/2024

really great, I think adding a few quiz and assignment would do nicely. I would recommend not use matlab, it is now available to everyone, use kicad, LTI or a slew of other open source programs instead. But I can highly recommend this course

By Arnold Palmer on 10/12/2022

The instructor makes it so easy to understand. I am really glad I joined the course, electricity looked very difficult, but I am hopeful that I will understand it. Thank you Ahmed.

By Michael Doll on 2/8/2022

I'm looking for a refresher on node and mesh analyses. I've skipped the first 30 sections, but am finding this refresher a great way to get back in the mindset for resolving other system (ventilation / road options / water options) analyses.

The content is good, but the pronunciation is not the best.

no v

By CHELESEA MILTON on 6/22/2020

The accent is a bit difficult to catch up on, content-wise, GOOD

By Muhammad Ebrahim Issack Boolaky on 6/6/2020

Lack of complex theory application
for instance, explanation of the electricity generator
I hope to have it in further sections.
