While discussing how to test a switch, Technician A says the action of the switch can be monitored by a voltmeter. Technician B says the continuity through the switch can be checked by measuring the resistance across the switch terminals using an ohmmeter. Who is correct?
A)A only
B)B only
C)both A and B
D)neither A nor B

Question

Quizplus · Accepted Answer

Both technicians are correct. Technician A's method of using a voltmeter to monitor the action of the switch can determine if the switch is properly opening and closing the circuit by observing changes in voltage. Technician B's method of using an ohmmeter to check for continuity through the switch by measuring resistance across its terminals can determine if the switch is capable of conducting electricity when it is in the closed position.
