Answer» Answer: 2) U/4 Explanation: LET Q be the charge on each CAPACITOR. Now, when battery is disconnected and another capacitor of same CAPACITY is connected in PARALLEL to the first capacitor, then voltage across each capacitor, V = q/2C Read more on Sarthaks.com - https://www.sarthaks.com/226974/capacitor-is-charged-with-battery-and-energy-stored-after-disconnecting-battery-another |
