Problem
Immediately after a switch is closed to begin charging an initially uncharged capacitor through a resistor, which statement best describes the circuit’s behavior?
(a) The capacitor acts like a short circuit, so the initial current is I0=V/R.
(b) The capacitor acts like an open circuit, so the current is zero immediately after the switch is closed.
(c) Because the resistor and capacitor share the battery voltage equally at the moment of switching, the initial current is I0=V/(2R).
(d) The resistor has no effect at the instant of switching, so an unlimited (infinite) current flows.
