Electric Power

Equation and meaning

\[P = VI\]

Electric Power Where : P is the Power,I is the Current,R is the Resistance,

Variables in this formula

P — Power
Power SI unit: W
VI — Vi
Enter this value unless it is the selected unknown.

How to use this calculator

  1. Leave one value emptyThe empty field is automatically treated as the unknown.
  2. Enter known values and unitsChoose N, kgf, dyn, SI or another compatible unit when available.
  3. Review the automatic answerThe result appears immediately and is substituted back into the formula to check the residual.
