How this calculator works
Voltage is V = IR.
Formula
V=IRVoltage from current and resistance.
Worked example
Verified example is a verified test case used by the calculation engine.
Assumptions and limitations
- Current may be signed.
- Resistance is non-negative.
- Use compatible units.
Methodology & sources

Frequently asked questions
What determines voltage sign?
With non-negative resistance, its sign follows signed current.
Is this Ohm's law?
Yes. This form solves V = IR.
