Voltage Calculator – Ohm's Law

Calculate voltage using Ohm's Law from current and resistance.

Current (Amps)

Resistance (Ohms)

Voltage Calculator Formula

V = I × R (Ohm's Law)

Current: 5A, Resistance: 10Ω → V = 50V

What is Ohm's Law?

Calculate electrical current from voltage and resistance.

Calculate electrical power in watts from voltage and current.

Calculate energy consumption in kWh and electricity cost.
