How to calculate ohms law voltage

This tool calculates ohms law voltage from Current (A), Resistance (Ω). Enter each quantity in its labelled field, then use the formula below to check the calculation.

Formula

current × resistance

Worked example

Current (A)
2
Resistance (Ω)
6

Applying the formula to these values gives 12 V.
