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.
Question 2
A resistor is made out of a long wire having a length L. Each end of the wire is attached to a terminal of a battery providing a constant voltage V0.
A current I flows through the wire. If the wire were cut in half, making two wires of length L/2, and both wires were attached to the battery (the end of both wires attached to one terminal, and the other ends attached to the other terminal), what would be the total current flowing through the two wires?
A) 4I
B) 2I
C) I
D) I/2
E) I/4
