Energy Stored in a Capacitor
संधारित्र में संचित ऊर्जा
In this Class 12 Physics topic from Electrostatic Potential and Capacitance, students learn how a charged capacitor stores electrical energy in the electric field between its plates. The topic develops the expressions U = ½CV², U = ½QV, and U = Q²/2C, showing how energy depends on capacitance, charge, and potential difference. It also connects the work done in charging a capacitor with the area under its charge–voltage graph and introduces energy density in an electric field.
