Class 12 Physics simulations · Electrostatic Potential and Capacitance

Charging an RC circuit

Watch a capacitor approach the battery voltage.

Open the simulation

What to notice

After one time constant, the capacitor reaches about 63% of the supply voltage.

Key relation

Vc = V₀(1 − e^(−t/RC))

Try this

Double resistance and observe the slower charging.

What you can change

• Resistance: 1 to 10 kΩ
• Capacitance: 100 to 1000 µF
• Supply voltage: 2 to 12 V
