Understanding AC Circuits

Unit 2

Measuring AC

An important activity in the study of electronics is measurement. Measurements are made in many types of electronic circuits. The proper ways of measuring ac should be learned. Common methods of measuring ac include the use of multimeters (VOMs) and oscilloscopes. Use of a multimeter is discussed in Understanding DC Circuits. This unit stresses the use and operation of oscilloscopes.
