Electric Power

Written by Jerry Ratzlaff on . Posted in Electrical Engineering

Power $$\:(P)\:$$ 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.

Electric Power (Watt) formulas

 $$\large{ Watts = \frac{Volts^2}{Ohms} = P = \frac{V^2}{R} }$$ $$\large{ Watts = Volts^2 \; Ohms = P = V^2 \; R }$$ $$\large{ Watts = Volts \; Amps = P = V \; I }$$ $$\large{ W = \frac{ m \; g \; h }{ t } }$$ (horsepower)

Where:

$$\large{ P }$$ = power

$$\large{ I }$$ = current

$$\large{ h }$$ = height

$$\large{ m }$$ = mass

$$\large{ R }$$ = resistance

$$\large{ g }$$ = gravitational constant

$$\large{ V }$$ = volt
