Effect of Voltmeter on RC Circuit Time Constant
A non-ideal voltmeter with finite internal resistance is used to measure the voltage across the resistor in an RC circuit. How does this measurement affect the circuit’s time constant?
A
It oscillates between two distinct values
B
It decreases due to the parallel resistance effect
C
It remains unchanged regardless of the voltmeter
D
It increases proportionally to the voltmeter’s resistance
