Two capacitor C(1) and C(2), charged wit...

Two capacitor `C_(1)` and `C_(2)`, charged with charges`q_(1)` and `q_(2)` then these are connected in series with an uncharged capacitor `C`, as shown in figure. As the switch `S` is closed :

A

C gets charged in any condition

B

C gets charged only when `q_(1)C_(2) gt q_(2)C_(1)`

C

C gets charged only when `q_(1)C_(2) lt q_(2) C_(1)`

D

C gets charged when `q_(1)C_(2) ne q_(2)C_(1)`

Text Solution

Verified by Experts

The correct Answer is:
D
Charge in the circuit flows only when potential difference across `C_(1)` is either greater or less than that across `C_(2)`
i.e. `(q_(1))/(C_(1)) ne (q_(2))/(C_(2)) :.q_(1)C_(2) ne q_(2)C_(1)`
