A)the ohmmeter is connected in parallel to the circuit and the circuit is turned on
B)the ohmmeter is connected in series to the circuit and the circuit is turned on
C)the circuit or component must first be disconnected from the power source, then the ohmmeter is connected in parallel with the component being tested
D)the circuit or component must first be disconnected from the power source, then the ohmmeter is connected in series with the component being tested

Question

Quizplus · Accepted Answer

Ohmmeters must be used on circuits or components that are disconnected from any power source to prevent damage to the meter and ensure accurate readings. The ohmmeter is then connected in parallel with the component to measure its resistance.
