Question 198Electricity/Electronics - 1st Asst/Chief70% to pass
To test fuses in an energized circuit, what testing apparatus or meter should be used?
AI Explanation
The correct answer is A) voltmeter.
To test fuses in an energized circuit, a voltmeter should be used. This is because a voltmeter measures the voltage across the fuse, which allows you to determine if the fuse is functioning correctly. If the voltage drop across the fuse is within the expected range, the fuse is likely good. The other options, such as a continuity tester, megohmmeter, or resistance meter, are not appropriate for testing fuses in an energized circuit, as they could potentially damage the fuse or the circuit.
