Develop essential physical sciences skills with expert instruction and practical examples.
Welcome to my course on AC circuits. This course covers most of the material typically covered in a introductory physics undergraduate course. In this course you will learn how to analyze AC circuits.
The course starts with simple AC circuits with a generator and a single electrical component. You will learn how to describe an AC signal in terms of an amplitude, frequency, and phase. You will also learn how to calculate RMS values of voltage and current and how they are related to peak values.
After, more complex circuits are solved with several electrical components. You will learn how to apply Kirchhoff's laws to AC circuits, how to calculate capacitive and inductive reactance, and use special techniques such as Phasor diagrams, to find the current amplitude and phase in an AC circuit. We will also cover energy and power in AC circuits.
You will learn how to calculate the power supplied by the generator, power dissipated by resistors, energy stored in inductors and capacitors. You will also learn about basic step-up and step-down transformers and how to calculate the voltages and currents on the primary and secondary sides of a transformer. This course has over 80 solved problems that will help you master the topic.
