A capacitor is charged by a battery. The battery is removed and another identical uncharged capacitor is connected in parallel. The total electrostatic energy of resulting system [NEET 2017]
Text Solution
Verified by ExpertsThe correct answer is:
D
Energy stored in a system of capacitors
Also, potential drop remains same in parallel across both capacitors.
Initially stored energy,
Finally, potential drop across each capacitor will be still V.
So, finally stored energy
