A potentiometer [type of variable resistor] can be tested with all the following tools EXCEPT:
A)test light
B)voltmeter
C)ohmmeter
D)digital lab scope (DSO)

Question

Quizplus · Accepted Answer

A test light, designed to check for the presence of voltage, is not suitable for testing a potentiometer, which requires measuring resistance or voltage variation across its terminals. Voltmeters, ohmmeters, and digital lab scopes (DSOs) can all be used to measure these properties accurately.
