Question

In the RC circuit pictured below, he switch has been closed for a long time, and the capacitor in the circuit is fully charged. When switch S is opened, the battery is not part of the circuit anymore and the capacitor starts discharging. The capacitance is C = 0.2 ?F, the resistance is R = 5 ?, and the voltage provided by the battery is ? = 12 V.

A. 1.2 ?C
B. 2.4 ?C
C. 3.6 ?C
D. 4.8 ?C
