| Two circuits and have charged capacitors of capacitance C, 2C and 3C with open switches. |
| Charges on each of the capacitor are as shown in the figures. On closing the switches |
 [JEE ONLINE 07-05-2012] |
A) No charge flows in [a] but charge flows from R to L in [b]
B) Charges flow from L to R in both and [b]
C) Charges flow from R to L in [a] and from L to R in [b]
D) No charge flows in [a] but charge flows from L to R in [b]
Correct Answer: C
Solution :
[c] Charge (or current) always flows from higher potential to lower potential. Potential\[=\frac{\text{Charge}}{\text{Capacitance}}\]
