Detailed explanation-1: -The most common unit of measurement on the electricity meter is the kilowatt hour [kWh], which is equal to the amount of energy used by a load of one kilowatt over a period of one hour, or 3, 600, 000 joules. Some electricity companies use the SI megajoule instead.
Detailed explanation-2: -Thus Watt-hour corresponds to the unit of work. Since the work done by a body is essentially converted into a form of energy, here we can say that Watt-hour is the unit of electrical energy and a Watt-hour meter will be used to measure electrical energy.
Detailed explanation-3: -Q. Commercial unit of electric energy is kilowatt hour (kWh).
Detailed explanation-4: -1 unit of electricity = 1 kWh. The electricity used is generally charged for in “unit of electricity’. Killowatt-hours is the product of watts x time (one killowatt = 1000 watts).
