Question

After removing battery from capacitor what will be charge on capacitor

Answer 1

The capacitor will start discharging because of leakage current. Leakage current is the unwanted current that that exist between the two plates. For general purpose we ignore this leakage current as it does not come into play. But if you are considering long delays, or storing charge in capacitor then it will come into play.

Answer 2

Answer:

Once you remove the battery, this difference in charge between the two plates remains indefinitely, until thecapacitor is connected to a circuit (such as a light bulb) through which itcan discharge.
