Electric Power Calculator
Calculate electrical power as voltage multiplied by current.
How to use
- Enter voltage V.
- Enter current I and calculate.
Capabilities and scope
The runner evaluates P=V×I for the entered operating or rating values.
How it works
It uses P=V×I.
Example
12 V at 2 A gives 24 W.
Useful for
- Estimate DC device power
- Convert voltage/current ratings to watts
Before you use it
- For AC, real power can differ because power factor and phase are not included.
Frequently asked questions
Is 230 V at 1 A always 230 W in AC?
Only at power factor 1; general AC real power requires power factor.
