Hello Everyone! Welcome to the free sample part "An Intro to Electric Circuits (EE101-Sample)". This is not a complete course. This is just a part of the main course "Electric Circuits I (EE101)". This part shows you how can you start the journey of becoming a circuits-designer.  In this introductory course, we will talk about the main fundamentals of the Electric Circuits along with a variety of different applications. I will keep adding samples of the main course here for treating you for enrolling in this free course.

I am intending to build the whole track for you to start from the beginners level all the way up to the advanced IC design level. I will share my 8-years of experience in designing Analog-Mixed ICs to help you get the required knowledge to become an excellent IC Designer. This course and the upcoming series of courses will make you ace during your studies of circuits.

So, If you like this introductory course and interested to become an Analog-Mixed/Digital Integrated Circuits Design Engineer, you can check out the complete course(s) under my profile.

Make sure you check the conclusion lecture for what is next after this course, what you need to become IC-Designer, coupons for my other courses and much more information.

The description of the main course is the following:

This course takes you through the basics and fundamentals of electric circuits. It starts with introducing the field of electrical engineering and electric circuits. After that, we go through the main electrical quantities and how are they related to each other. When we clearly have this, we move to the circuit basic analysis techniques such as Ohm's law, Kirchhoff's Voltage Law (KVL) and Kirchhoff's Current Law (KCL). More concepts will build up from there.

The following list sums the contents of this course: 

  1. Introduction to Electrical Engineering and Electric Circuits.

  2. Basic Analysis Techniques of Electric Circuits.

  3. Advanced Analysis Techniques of Electric Circuits.

  4. An Intro on how to read Schematics and Simulate Circuits in Pspice.

  5. An Intro to AC Circuits.

The Course is still under developing and it will include the following points as well: 

Advanced Analysis Techniques of Electric Circuits

- Nodal Analysis

- Mesh Analysis

- Thevenin's Theorem

- Norton's Theorem

- Concept of Linearity and Superposition

- Concept of Source Transformation

- How to Maximize the Power to a load - Concept of Max. Power Transfer

- Difference between Max. Power Transfer and Max. Voltage Transfer

How to read a Schematic and Simulate circuits in Pspice

- What is Schematic and how to read it?

- Other alternatives for a schematic

- Simulating Circuits using Pspice

An Intro to AC Circuits
- AC Sources

- AC-Circuit elements

- Phasors Meaning

Conclusion and what can be next?

Interview Questions: I will pack my courses with real interview questions based on what I personally had from my experience.

IC Design Track: The course is part of the IC Design Track that I am working on. This track aims at covering all circuits basics, analog-IC design basics, digital-IC design basics.   

Circuit-Designers IQ Questions: This course contains some of these questions. This type of questions is challenging and you will be intrigued by it to think out of the box!.

Style of the course: We start by going over the theory or theoretical analysis. After building a concrete understanding, we move to the examples and real applications part. For examples, we have examples for each concept.

Simulations: Pspice simulations are included in this course. I believe practising on Pspice, circuit simulations and design using computer tools is a must from the early stage of learning how to build circuits.

Exciting Real applications and Life-Hacks!: We are dealing with electric and electronic circuits every day or even every hour. In this course, I will share some really good life-hacks and analyze some everyday applications.

One-On-One Assistance: You can ask all your questions in the Q&A section at any time, I usually answer within two days.

Regularly updated:  This course will be regularly updated. I will keep adding basic concepts from the same level to it.

I will keep this course at the elementary level to make it to the beginners level or people who want to review the basics again. For IC design, It is super important to have very-good established fundamentals of Electric-Circuits.

That is it, see you in the Q&A area!

Who this course is for:

  • Junior Electrical Engineering Students
  • Anyone interested in mastering the fundamentals of electric circuits and electronics.
  • Any student taking an electricity or electronics class.
  • First year engineering students.
  • People who want to review the basics of electric circuit elements
