pie chartPower is the rate of doing work and is measured by the amount of foot pounds of work done in a particular unit of time. A horsepower is a measure of power.

Formula

\(Watts = \frac{Volts^2}{Ohms}\;\; = \;\;P = \frac{V^2}{R}\)

\(Watts = Volts^2 \;\cdot\; Ohms\;\; = \;\;P = V^2 \;\cdot\; R\)

\(Watts = Volts \;\cdot\; Amps\;\; = \;\;P = V \;\cdot\; I\)
