课程详情

Alternating current (AC) is the type of electricity commonly used throughout the world to connect power plants, homes, and businesses. This course will give you an understanding of why AC is used and will allow you to design and analyse circuits which use AC electricity.

You will learn how to calculate voltages, currents and power in circuits with AC sources, how to calculate RMS voltage and current, how to handle both sinusoidal and non-sinusoidal sources, how to use relays and transistors as switches, how to design circuits with transformers, how to model realistic, non-ideal transformers, how to design and build simple DC power supplies and rectifiers, and we will explore concepts of maximum power transfer with AC circuits. In terms of sequencing, this course would be suitable for students who already have a working knowledge of basic DC circuits (such as our other MOOC Circuits for Beginners).

课程大纲

A working knowledge of DC circuits. Completion of our course Circuits for Beginners is recommended.

课程简介

In this course, you will learn all about circuits with alternating current (AC). The course shows how to design and analyse AC circuits, and concepts like phasors and power factor are explained. We also cover transformers, fuses, relays, and the use of transistors as switches. The course is the second in our series on electronics and a working knowledge of DC circuits is assumed.
