RC Circuits: an RC Circuit Is Connected Across an Ideal

question 6

Multiple Choice

RC circuits: An RC circuit is connected across an ideal DC voltage source through an open switch. The switch is closed at time t = 0 s. Which of the following statements regarding the circuit are correct? (There may be more than one correct choice.)

• A) The capacitor charges to its maximum value in one time constant and the current is zero at that time.
• B) The potential difference across the resistor and the potential difference across the capacitor are always equal.
• C) The potential difference across the resistor is always greater than the potential difference across the capacitor.
• D) The potential difference across the capacitor is always greater than the potential difference across the resistor
• E) Once the capacitor is essentially fully charged, there is no appreciable current in the circuit.
