Q. Across each of two capacitors $1\ \mu$F and 4 $\mu F$, a potential difference of 10 V is applied. Then positive plate of one is connected to the negative plate of the other, and negative plate of one is connected to the positive plate of the other. After contact
A) Charge on each is zero
B) Charge on each is same but non-zero
C) Charge on each is different but non-zero
D) None of the above
Explanation
(c) Stored charge on capacitor becomes zero only when it is discharged through resistance or when two capacitors of equal capacitances are charged and then connected to opposite terminals. Here the capacitances are different.
