Final answer:
In circuit testing, it is crucial to isolate components and turn off the power to ensure safety and accurate readings.
Explanation:
False. When performing a voltage drop test in a circuit, the components of the circuit must be isolated, and the power should be turned off for accurate measurements. Connecting an ohmmeter to a 'live' circuit with a voltage source can damage the meter.
