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.
B. 2.4 ?C
C. 3.6 ?C
D. 4.8 ?C In the RC circuit pictured below, he switch has been closed for a long time, and the capacitor in the circuit is fully charged.

Explanation / Answer
a)
Qo=CV=0.2u*12
Qo=2.4 uC
b)
T=RC =5*0.2u
T=1 us
