Increasing the resistance of a voltmeter's series resistance
A) converts it to an ammeter.
B) allows it to measure a larger voltage at full-scale deflection.
C) allows it to measure a smaller voltage at full-scale deflection.
D) enables more current to pass through the meter movement at full-scale deflection.

Question

Quizplus · Accepted Answer

Increasing the resistance of a voltmeter's series resistance allows it to measure a larger voltage at full-scale deflection. This is because the higher resistance limits the current through the meter, allowing it to safely measure higher voltages without exceeding its maximum current capacity.
