Doubling the capacitance in an RC circuit
A)doubles the time constant of the circuit.
B)halves the time constant of the circuit.
C)has no effect on the time constant of the circuit.
D)has no effect on the rate at which energy is dissipated by the circuit.
E)None of these is correct.

Question

Quizplus · Accepted Answer

The time constant of an RC circuit is given by the product of the resistance and capacitance, RC. If the capacitance is doubled, then the time constant becomes 2RC. Therefore, doubling the capacitance doubles the time constant of the circuit.
