70% to pass

When performing an absence-of-voltage test, a live-dead-live test may be required in conjunction with the absence-of-voltage test. What is the purpose of the live-dead-live test?

AThe live-dead-live test proves the functional ability of the voltage tester to measure voltage prior to and after conducting the absence-of-voltage test which validates the results of the absence-of-voltage test.
BThe live-dead-live test proves the functional ability of the voltage tester to measure voltage after conducting the absence-of-voltage test which validates the results of the absence- of-voltage test.
CThe live-dead-live test proves the functional ability of the voltage tester to measure voltage prior to conducting the absence-of-voltage test which validates the results of the absence-of- voltage test.
DThe absence-of-voltage test proves the functional ability of the voltage tester to measure voltage prior to and after conducting the live-dead-live test which validates the results of the live- dead-live test.
AI Explanation

The correct answer is A. The purpose of the live-dead-live test when performing an absence-of-voltage test is to prove the functional ability of the voltage tester to measure voltage prior to and after conducting the absence-of-voltage test. This validates the results of the absence-of-voltage test, ensuring that the voltage tester is working properly and providing accurate readings. The other options are incorrect because: B) The live-dead-live test is not performed solely after the absence-of-voltage test. C) The live-dead-live test is not performed solely before the absence-of-voltage test. D) The absence-of-voltage test does not validate the live-dead-live test; the live-dead-live test validates the absence-of-voltage test.
