Question 2
A resistor, an uncharged capacitor, a dc voltage source, and an open switch are all connected in series. The switch is closed at time t = 0 s. Which one of the following is a correct statement about the circuit?
A) Once the capacitor is essentially fully charged, there is no current in the circuit.
B) The potential difference across the resistor is always equal to the potential difference across the capacitor.
C) Current flows through the circuit even after the capacitor is essentially fully charged.
D) The capacitor charges to its maximum value in one time constant.
E) The capacitor charges to its maximum value in two time constants.
