To prevent meter loading,a voltmeter used to make transistor circuit voltage measurements should have an input impedance of ________.
A) 10 kW
B) 100 kW
C) 1 MW
D) 10 MW

Question

Quizplus · Accepted Answer

To prevent meter loading, a voltmeter should have a high input impedance. An input impedance of 10 MΩ (option D) is high enough to minimize the effect of the meter on the circuit being measured, ensuring accurate voltage readings without significantly altering the circuit's behavior.
