Detailed explanation-1: -Electricity is measured in units of power called Watts, named to honor James Watt, the inventor of the steam engine. A Watt is the unit of electrical power equal to one ampere under the pressure of one volt.
Detailed explanation-2: -The watt (symbol W) is the SI unit of power, and is defined as the power which in one second gives rise to energy of one joule (1 J = 1 W⋅s).
Detailed explanation-3: -A body is said to have one watt of power if it can perform one joule of work in one second. Power is defined as the rate at which work is performed, or energy is converted. P o w e r ( P ) = w o r k ( w ) t i m e ( t ) = J s. The SI unit of power is the watt.
Detailed explanation-4: -Units of power are ergs per second (erg/s), horsepower (hp), and foot-pounds per minute.
Detailed explanation-5: -What is a unit of electricity? One unit of electricity is equal to one kilowatt-hour. It is the amount of power required to use an appliance of 1000 watt power rating for an hour.
