B) Technician B only
C) Both A and B
D) Neither A nor B

Question

Voltage drop is indeed an effective measurement of resistance in a circuit because it directly shows how much potential difference is lost across a component or conductor, indicating resistance. It is often more practical for finding issues in a circuit under load, compared to using an ohmmeter which measures resistance without the circuit being powered.
