Understanding DC Circuits

Unit 2

Measuring Voltage, Current, and Resistance

Another important activity in the study of electronics is measurement. Measurements are made in many types of electronic circuits. The proper ways of measuring resistance, voltage, and current should be learned. These are the three most common electric measurements.

UNIT OBJECTIVES

Upon completing this unit, you will be able to do the following:

1. Connect an ammeter in a circuit and measure current.

2. Demonstrate how the voltmeter, ammeter, and ohmmeter are connected to a circuit.

3. Measure current, voltage, and resistance of basic electronic circuits.

4. Compare calculated and measured values of a circuit.

5. Demonstrate safety while making electric measurements.

6. Demonstrate proper, safe use of an ...
