What you'll learn

  • Circuits Designers IQ Questions to challenge you and push you to think out of the box!
  • Real interview questions based on what I personally had from my experience.
  • Electric Circuit Basics and Fundamentals.
  • The reality of Ohm's law and where did it come from?

Course content

1 section • 16 lectures • 1h 35m total length

  • Announcement0:34
  • Course Motivation1:39

    Kick off the electric circuits course with an introduction to abstraction, course contents, textbooks, and references, and connect circuits to real-world applications like consumer electronics and multicore processors.

  • What is Abstraction?4:22

    Learn how abstraction simplifies circuit analysis by modeling a complex device as a simple resistor, using Ohm's law to relate voltage, current, and resistance.

  • A Road Map to become a Circuit Designer1:23

    Explore a three-level pathway to become a circuit designer, from elementary electric and electronic circuits to intermediate and advanced design, including semiconductor physics, signals and systems, and control theory.

  • A Real Application: The Cell Phone4:24

    Explore the cell phone circuit architecture as an integrated system of amplifiers, oscillators, and frequency converters, highlighting subsystems, blocks, and devices within a harmonious, compatible design.

  • What is Electric Charge?7:00

    Examine electric charge, its positive and negative discrete nature, conservation, and charge carriers such as electrons, protons, ions, while linking movement to current and voltage to charge separation.

  • Definition of Electric Current?15:37

    Compare conductors, semiconductors, and insulators in charge mobility and define current as charge flow over time, depending on density, cross-section, and charge speed, including DC and AC.

  • Definition of Voltage?10:00

    Voltage is the energy difference a unit charge experiences between two points. VAB defines this difference relative to a reference like ground; batteries convert chemical energy to electrical energy.

  • Electric vs. Electronic Circuits1:47

    Explore the difference between electric and electronic circuits, noting that electric circuits use only passive devices like resistors and capacitors, while electronic circuits add active devices such as transistors.

  • Problem # 61:22

    Compute the current from a charge rate of 45,000 coulombs per hour, convert to seconds to obtain 12.5 amps, and determine that a 10-amp fuse will blow.

  • Lumped Electric Circuits Elements10:54

    Explore lumped electric circuit elements, distinguishing passive and active types, independent versus dependent sources, and V–I relationships like Ohm's law for resistors in dc circuits.

  • Electric Sources - Voltage Source and Current Source4:53

    Explain independent and dependent sources, covering voltage and current sources, and introduce four dependent sources: cccs, vccs, ccvs, and vcvs.

  • Ohm's Law? Is it 100% correct!?10:40

    Demonstrate how Ohm's law arises from local versus global voltage–current relations, emphasize the linear term and resistance concept, and explain electron collisions in conductors.

  • Linear vs. Non-Linear Resistors6:22

    Differentiate linear from nonlinear resistors: linear resistors have constant resistance and V–I line, while nonlinear resistors vary with current or voltage, and Ohm's law applies only at constant temperature.

  • From Physics to KVL13:04

    Derive Kirchhoff's voltage law from Faraday's law, showing the line integral around a closed loop is zero, then apply it to loops with resistors and batteries.

  • Bonus: What is Next?1:14

Requirements

  • Basic calculus/mathematics
  • Have the passion to learn circuits and become a hardware engineer!
  • High School Physics

Description

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.


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.


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!
