The internal resistance of any meter is only effective if the meter is set on the ________ scales.
A) ammeter
B) ohmmeter
C) voltmeter
D) None of these

Question

Quizplus · Accepted Answer

The internal resistance of a meter is effective only on the voltmeter scales. This is because in a voltmeter, the internal resistance is connected in series with the circuit being measured, affecting the total resistance and ultimately the voltage measurement. In ammeter and ohmmeter scales, the internal resistance is connected in parallel with the circuit being measured, which does not affect the current or resistance measurements.
