A capacitor is charged with a battery and energy stored is U After disconnecting battery another capacitor of same capacity is connected in parallel to the first capacitor. Then energy stored in each capacitor is
Text Solution
Verified by ExpertsThe correct answer is:
B
Let q be the charge on each capacitor.
Energy stored,
Now, when battery is disconnected and another capacitor of same capacity is connected in parallel to the first capacitor, then voltage across each capacitor,
q/2C
Energy stored
.
