An RC circuit is connected across a DC voltage source through an open switch. The switch is closed at t = 0 s. Which of the following is a correct statement regarding the circuit?
A) The capacitor charges to its maximum value in one time constant.
B) The capacitor charges to its maximum value in two time constants.
C) The resistor and the capacitor share the applied voltage equally as a function of time.
D) The current flows through the circuit even after the capacitor is fully charged.
E) Once the capacitor is fully charged, there is no current in the circuit.

Question

Quizplus · Accepted Answer

Once the capacitor is fully charged, there is no current in the circuit because the capacitor acts as an open circuit in a DC steady state.
