A measure of power or rate of energy.
The SI unit of power, equal to 1 joule per second. In electrical terms it is the energy expended per second when a current of 1 ampere flows between two points on a conductor between which there is a potential difference of 1 volt. I watt = 10⁷ ergs per second.
A unit of electrical power. One watt is the power produced by 1 ampere of current flowing with a force or pressure (i.e., electromotive force) of 1 volt. In SI units, 1 w equals 1 J/sec. In other units, 1 w equals 1 newton m/sec. This is also equal to 0.7376 ft-lb/sec.
Unit that measures how much electric energy is being used in one second.
In the domain of electric power, we encounter a fundamental measurement known as the unit of power. This unit, expressed in watts, represents the quantification of electrical energy. Remarkably, the power in watts can be calculated by multiplying the value of volts, which signifies the electrical potential difference, with the measurement of amperes, which represents the electric current flowing through a circuit.
