When a current I is passed through a resistance R, the resulting power P dissipated in the resistance is equal to the square of the current I multiplied by the resistance R:P = I2R
By substitution using Ohm's Law for the corresponding voltage drop V (= IR) across the resistance:P = V2 / R = VI = I2R
