The power dissipated in a direct current DC circuit element is given by the formula P V I where V is the voltage across the element and I is the current in the circuit. Losses in Electrical Machines Formulas and Equations. Single- and three-phase power are both terms describing alternating current AC electricity.
In case of both inductive and capacitive loads.
Basic Electrical Quantities Formulas. When the values of current and voltage are given the formula for finding power is. Z R2 XL XC2. Multiply the value of the 80A load by 125 100A.
