An RC Circuit Is Connected Across an Ideal DC Voltage

question 46

Multiple Choice

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.
