A parallel-plate capacitor has capacitance 5.20 μF. The capacitor was origionaly connected to a 1.50 V battery? (b) If the battery is disconnected and the distance between the charged plates doubled, what is the energy stored? Note: When disconnected, the charge on the capacitor must remain the same as when disconnected. A parallel-plate capacitor has capacitance 5.20 μF. The capacitor was origionaly connected to a 1.50 V battery? (c) The battery is subsequently reattached to the capacitor, but the plate...

A parallel plate capacitor with capacitance C0 is connected to a battery with voltage V0 and is charged fully to a charge Q0. There is an electric field E0 between the plates and energy U0 stored in the capacitor. With the battery still connected, the area of the plates are doubles and the plates are pulled to a distance three times its original distance (while still being small compared to the size of the plates). Find (in terms of the...
