1. For the circuit shown in Fig. 19-46, what happens when the switch S is closed?
(a) Nothing. Current cannot flow through the capacitor.
(b) The capacitor immediately charges up to the battery emf.
(c) The capacitor eventually charges up to the full battery emf at a rate determined by R and C.
(d) The capacitor charges up to a fraction of the battery emf determined by R and C.
(e) The capacitor charges up to a fraction of the battery emf determined by R only.

2. The capacitor in the circuit shown in Fig. 19-47 is charged to an initial value Q. When the switch is closed, it discharges through the resistor. It takes 2.0 seconds for the charge to drop to 1/2Q. How long does it take to drop to 1/4Q?
(a) 3.0 seconds.
(b) 4.0 seconds.
(c) Between 2.0 and 3.0 seconds.
(d) Between 3.0 and 4.0 seconds.
(e) More than 4.0 seconds.
