Question 487Electricity & Electronics - QMED
70% to passTo test fuses in an energized circuit, what testing apparatus or meter should be used?
Aresistance meter
Bvoltmeter
Cmegohmmeter
Dcontinuity tester
AI Explanation
The correct answer is B) voltmeter. To test fuses in an energized circuit, a voltmeter should be used. This is because a voltmeter measures the potential difference across a component, which allows you to determine if the fuse is functioning properly by checking if the voltage drop across it is within the expected range. Other devices like a resistance meter, megohmmeter, or continuity tester are not suitable for testing fuses in an energized circuit, as they could potentially cause damage or create unsafe conditions.
