Which of the following statements is LEAST-Likely true?
A) Checking voltage drops as a preventive maintenance measure will catch potential problems before they fully develop.
B) A small amount of voltage drop through the fuse link, which is a smaller wire than the rest of the circuit, is normal.
C) There are no fuse links in the ground circuit, so lower voltage drop (0.1 volt) is desired.
D) When performing a voltage drop test, remember that current must not be running through the circuit.

Question

Quizplus · Accepted Answer

Voltage drop tests are actually performed while the circuit is under load, meaning current must be flowing through the circuit to accurately measure the voltage drop. This is because the purpose of the test is to identify excessive resistance that only becomes apparent under these conditions.
