Electric Power

What Does Electric Power Mean?

Electric power is defined as the rate at which electrical energy is consumed in an electrical circuit. The SI unit of power is the watt, which is one joule per second. Although sources such as electric batteries can supply electric power, it is mostly produced by electric generators. With the help of an electric grid, electric power is supplied by the energy industry to homes and other industries.


Techopedia Explains Electric Power

Electric power (P) can be calculated as energy consumption (E) divided by the time consumed (t):

P = E/t, with P in watts, E in joules and t in seconds

In the case of electric power consumption by homes and businesses, it is mostly sold by the kilowatt hour, which is running time in hours multiplied by the power in kilowatts. An electricity meter is used to measure the amount of power consumption. Electric power is considered as a low-entropy form of energy.

Electric power generation is considered clean, as there are no byproducts produced. As it is a necessity for businesses and customers to operate commercial and domestic appliances, the electric power generation industry is considered as part of the public utility infrastructure.
