This is the only course with everything you need to know about the basics of electric circuits for beginners. This electric circuit masterclass starts with the basic concepts of electricity to the level you will be very familiar with circuits.

Throughout the course, you will learn:

**Basics concepts of electric circuits:** This will help you understand the 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 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:** An introduction to operational amplifiers, including inverting, non-inverting, summing, difference, and cascaded amplifiers; these amplifiers are helpful in inverting or amplification or adding or subtracting different input signals.

**Capacitors and inductors:** These components are essential 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 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 what we have in our homes. We will learn about them and the difference between them and AC circuits.

**Analysis of AC circuits:** In this part, we will start analyzing our AC circuits with the different theorems 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 to increase your knowledge about electric circuits.

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