Alternating Current

Learn the basic AC characteristics of voltage.

Prerequisites

This lesson was designed for participants familiar with Ohm??s Law.

Description

This is the fifth lesson in the iKNOW® Electrical Theory for Troubleshooters Library. This lesson teaches the basic AC characteristics of voltage, including how voltage changes over time. The participant is also instructed in using sine waves to interpret the frequency of
AC voltage.

Objectives

State the basic operating AC Characteristics of voltage. Explain how AC voltage changes over time. Define sine wave and cycle. Interpret the frequency of AC voltage using a sine wave. Explain RMS voltage vs. peak voltage.
