Electrical Power The amount of electrical power or power that a circuit performs over a period of time is called electric power or energy. Energy = Power X time energy single joule, commercial single kilowatt-hour. One kilowatt-hour = one unit energy is measured using an energy meter.
short description:-
Electric power is the rate of time per unit, where the electric power is transferred by an electric circuit. SI unit of power watts, one mesh per second.
Electric power is usually produced by electric generators, but can be supplied by sources such as electric batteries. It is usually supplied to businesses and homes through the electric power grid through the electricity industry. Electric power is typically sold by kilowatt-hours (3.6 megawatts), which is multiplied by the number of kilowatt-hours produced by the clock. Electric utilities measure electricity using a power meter, which keeps the total amount of electricity supplied to a customer.
Electric power provides a low entropy power and carries long distances and can be converted to other energy such as speed, light or heat with high energy efficiency.
Electricity is the rate of work that the power can do. The current I amperes and voltage volts are expressed as P = vi, and the unit is W. Also used as a variety of energy sources, electric power to do business is also commonly called electricity.
