4. TERMS, SYMBOLS AND UNITS OF
MEASUREMENT
Term Description Symbol Unit of Meas. Symbol
Charge Quantity of Accumulated Electrons Q Coulombs C
Voltage Electromotive Force E/V Volts V
Current Rate of Electron Flow I Amps A
Resistance Opposition to Electron Flow R Ohms Ω
Power Rate of doing Electrical Work P Watts W

7. Flow of
Electrons in a
copper wire

8. Using a Multimeter: Measuring
Resistance
Using the Ohmmeter Ω
1. Measures resistance in a circuit.
2. The circuit must be “dead.”
3. Choose the Ω setting on the meter.
4. Insert the Red (+) test lead into the voltage/Ω connector on the meter.
The black (-) test lead should be in the COM connector
5. If the component to be measured is mounted on a printed circuit board
then disconnect one end of the component to be measured from the
circuit.
6. Place the leads of the meter across (in parallel) the component to be
measured.

9. Using a Multimeter: Measuring
Voltage
V V
Using the Voltmeter
1.Measures the electromotive force (voltage) between two points.
2.The circuit must be “live.”
3.Choose the AC voltage or DC voltage setting on the meter.
4. Insert the Red (+) test lead into the voltage/Ω connector on the
meter. The black (-) test lead should be in the COM connector
5. Place the leads of the meter across (in parallel) the component
to be measured.

10. Using a Multimeter: Measuring
Current
Using the Ammeter
A
1. Measures electron flow (current) in a circuit.
2. The circuit must be “live.”
3. Choose the AC amperage or DC amperage setting on the meter.
4. Move the red test lead from the voltage/Ω connector to the
amperage connector on the meter.
5. Break the circuit and place the meter in series with the component
to be measured.
