OS-ELE-103 AC Electricity

Overview

In contrast to direct current (DC), which only flows in one direction, alternating current (AC) periodically reverses direction and continuously changes its magnitude with time. In this course, you will learn about electromagnetism, understand how alternating current is produced, and how electrical devices operate.

By the end of this course, you will be able to

• Define electromagnetism and induction
• Define a wave cycle and frequency
• Understand how an AC waveform is produced
• Identify the symbols for inductors, solenoids, and relays
• Identify the components and functions of a transformer
• Identify the components and functions of a capacitor
