Checking for excessive circuit resistance is being discussed. Technician A says voltage drop testing is used to identify excessive unwanted resistance in the circuitry. Technician B says measuring resistance is the most accurate method. Who is correct?
A)Technician A
B)Technician B
C)Both A and B
D)Neither A nor B

Question

Quizplus · Accepted Answer

Voltage drop testing is a practical method to identify excessive resistance in a circuit under load, as it measures the actual voltage loss across components or connections. Measuring resistance directly with an ohmmeter can be less accurate because it doesn't account for the circuit's behavior under load.
