The circuit?

• A) Current flows through the circuit even after the capacitor is essentially fully charged.
• B) Once the capacitor is essentially fully charged, there is no current in the circuit.
• C) The capacitor charges to its maximum value in one time constant.
• D) The potential difference across the resistor is always equal to the potential difference across the capacitor.
• E) The capacitor charges to its maximum value in two time constants.
