Voltage drop testing is being discussed. Technician A connects the red voltmeter lead to the most positive side of the circuit being tested and the black lead to the most negative side or part of the circuit being tested. Technician B says the test must be conducted with the circuit operating with normal amounts of current. Who is correct?
A)A only
B)B only
C)both A and B
D)neither A nor B

Question

Quizplus · Accepted Answer

Both Technician A and Technician B are correct. Technician A's method of connecting the voltmeter leads is the standard procedure for voltage drop testing, ensuring accurate measurement of potential difference across a component or section of a circuit. Technician B's statement is also correct because for a voltage drop test to be meaningful, the circuit must be operating under normal load conditions to accurately assess how it performs under typical operating conditions.
