Question 487Electricity & Electronics - QMED

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.
