This energy is stored in the electric field. The capacitance of a capacitor is a bit like the size of a bucket. Capacitance And Charge On A Capacitors Plates Capacitor Wikipedia Giant Energy Density And High Efficiency Achieved In Bismuth Energy stored in capacitor while capacitor is connected across a battery charges come from the battery and get stored in the capacitor plates. Electrical energy in capacitor . And the energy that was stored in the capacitor turns into light and heat that comes out of the light bulb. Energy stored in a capacitor is electrical potential energy and it is thus related to the charge q and voltage v on the capacitor. Voltage represents energy per unit charge so the work to move a charge element dq from the negative plate to the positive plate is equal to v dq where v is the voltage on the capacitor. Capacitor energ...
