Class 12 Physics simulations · Electrostatic Potential and Capacitance

Energy stored in a capacitor

Charge a capacitor and read the energy versus voltage.

Open the simulation

What to notice

Stored energy grows with the square of the voltage.

Key relation

U = ½CV²

Try this

Double the voltage — the stored energy becomes four times larger.

What you can change

• Capacitance: 1 to 100 µF
• Voltage: 1 to 24 V
