What is Electric Power and how to derive equation and unit for electric power physics.
Electric power is defined as the rate at which electrical energy is consumed in an electrical circuit.
or
Electrical work done per unit time Is know as power in physics.
Electric power is denoted by P and it's unit watt. other units of electric power are mega watt and kilo watt.
There are three different equation and are equally valid for calculation of electrical power. these three equations are.
P=w/t (power is equal to work done per unit time, P=VI (power is equal to voltage time current) and P=current square times resistance.
which one of these equation to be used depends on the given quantities.
we have derived these equations and along with the unit of power.
If the potential difference of one volt causes current of ampere the electrical power will be equal to one.
