Ohm's Law Calculator – Electrical Formula Made Easy

Ohm’s Law states that Voltage (V) = Current (I) × Resistance (R). This calculator helps you find any one value when the other two are known.

It is widely used in electrical engineering, electronics, and circuit analysis.

For example, if current is 2A and resistance is 5Ω, voltage is 10V.
