Class 12 Physics simulations · Current Electricity

Ohm’s law circuit

Change battery voltage and resistance to control the current in a closed circuit.

Open the simulation

What to notice

At fixed resistance, twice the voltage gives twice the current.

Key relation

V = IR

Try this

Double the resistance and notice how the charge flow slows.

What you can change

• Battery voltage: 1 to 24 V
• Resistance: 2 to 40 Ω
