An RC circuit contains a battery, a switch, a resistor, and a
capacitor – all connected in series. Initially, the switch is
open and the capacitor is uncharged. Which one of the
following statements correctly describes the current in the circuit
during the time the capacitor is charging?
A.
The current is increasing with increasing time.
B.
The current is constant with increasing time.
C.
The current is decreasing with increasing time.
D.
The current increases for the first half of the time until the
capacitor is fully discharged, and then decreases during the second
half of the time.
E.
The current can either increase or decrease with increasing time
depending on the value of the time constant.
