Power Formula

It is clear that Energy is the capacity to do work. The Energy consumed to do work in unit time is called Power. It is denoted by P.

Power Formula is given by

$P=\frac{E}{t}$

or

$P=\frac{W}{t}$

Where E = Energy Consumed to do work

            W = Work done and

            t = Time taken.

In any electrical circuit, the power is calculated using the 3 formulas

power

In terms of Voltage and current it is given as

$P=V\times I$

In terms of current and resistance it is given as

$P=I^2 R$

In terms of voltage and resistance it is given as

$P=\frac{V^2}{R}$

Where V = voltage applied across the two ends,

            I = Current flowing in the circuit and

           R = Resistance.

Power formula is used to calculate the Power, Voltage, current or resistance in any electrical circuit. It is expressed in watts.
