The big power Formulas: Formula 1 - Electrical (electric) power equation: Power P = I × V = R × I2 = V2 ⁄ R
where power P is in watts, voltage V is in volts and current I is in amperes (DC).
If there is AC, look also at the power factor PF = cos φ and φ = power factor angle
(phase angle) between voltage and amperage. Formula 2 - Mechanical (mechanic) power equation: Power P = E ⁄ t = W ⁄ t
where power P is in watts, energy E is in joules, and time t is in seconds. 1 W = 1 J/s Scroll down to related links and look at "Formulas and calculations - Electricity and Electric Charge".

∙ 14y agoPower in electrical formulas is measured in watts (W) The primary fomula is simply: W=ExI where E is volts and I is current measued in amps so volts times amps is equal to the power measured in watts. Also W=R x I squared where R is the resistance measured in ohms Also W= E squared/ R
