The word you're looking for is "watt." A watt is a unit of power that measures how fast electrical energy is used.
Watt is a unit of power. 1 Watt = 1 Joule/second; joule is the unit for energy.
The unit to measure the amount of electrical energy is the kilowatt-hour (kWh). It is commonly used by utility companies to bill customers for electricity consumption.
kilowatt-hour (kWh)
Energy consumption or electrical energy is measured in kilowatt-hours (kWh). It is a unit used to represent the amount of energy used by an electrical device over time.
Air conditioning involves the transformation of electrical energy into thermal energy. The electrical energy is used to power the air conditioning unit, which then removes heat from the indoor air, cooling it down.
The unit of measurement for electrical energy used in the home is the kilowatt hour, and this is the unit which the electricity supply company uses to work out your bill.
In SI, the same unit is used for any type of energy: the joule.
Lots of units are used to measure electricity, depending on what aspect you want to measure. For example: Voltage is measured in volts Current is measured in amperes Resistance (as well as impedance) is measured in ohms Power is measured in watts Capacitance is measured in coulomb Inductance is measured in henries etc.
Watt is a unit of power. 1 Watt = 1 Joule/second; joule is the unit for energy.
The kWh (kilowatt-hour)
In SI, the same unit is used for any type of energy: the joule.
One energy unit starting with C is a calorie, which is a unit of energy commonly used in nutrition to measure the energy content of food. Another energy unit is a coulomb, which measures electrical charge.
The unit to measure the amount of electrical energy is the kilowatt-hour (kWh). It is commonly used by utility companies to bill customers for electricity consumption.
kilowatt-hour (kWh)
Power; its SI unit is watt. Please note that this is notspecifically an electrical unit; "power", and the unit "watt", is the rate of energy conversion, and can be used anywhere where energy is converted - whether "work" is involved, or some other (non-mechanical) energy.
The unit used to describe the amount of electrical energy provided by an energy source is the kilowatt-hour (kWh). It represents the amount of energy consumed or produced by using 1 kilowatt of power for 1 hour.
Watts. Also for any other type of power (energy / time), that is, for transfer of energy that is not electrical in nature.
