The Electrical Power calculator computes the power based on Ohm's Law using electrical potential or voltage (V) and current (I).
INSTRUCTIONS: Choose your preferred units and enter the following:
Electrical Power: The calculator returns the electrical power in watts. However, this can be automatically converted to other power units via the pull-down menu.
For more information on the relationship between electrical power, current, resistance and potential, see the Ohm's Law Calculator.
