A device used to indicate instantaneous power usage.
Square meter is area and Kilowatt is energy. There is no equivalent.
In the same place the regular kilowatt hour meter was installed.
It is not power which is measured in homes, but energy consumption. Electricity companies charge for energy consumption in kilowatt hours (kW.h). This is done using an energy meter (also known as a 'watt-hour meter' or 'kilowatt-hour meter'), which monitors the supply voltage, and the in-phase component of the load current.
The meter on the side of your house is a watt meter. You are charged for the electricity that you use in kilowatt/hours. See related links below
The watt (or kilowatt) is a unit of power (energy/time). Kilowatt per unit area, for example, kilowatt per square meter, doesn't have a special unit name, but the thing measured is called intensity.
'Balanced loads' apply to three-phase a.c. loads. A three-phase kilowatt hour meter will measure both balanced and unbalanced loads, when correctly connected.
An electricity meter is an energy meter, and measures the amount of energy, expressed in kilowatt hours, you have purchased from your electricity supply company.
The kilowatt hour (KWHr) measures electricity use.
Electric meters measure kilowatt hours.
An electricity meter
A wattmeter measures power, which is the rate of doing work, expressed in watts.An energy meter measures the amount of energy consumed, usually in kilowatt hours.The meter on the wall of your house is an energy meter.
Take the amount of kWh that the meter states that you have used and multiply it by the cost of a kWh in your area.Another AnswerSubtract the energy meter reading from the previous billing period from that from the current billing period to determine the number of kilowatt hours used during that period. Multiply this difference by the cost per kilowatt hour charged by your energy provider. Note, however, some energy providers have a complicated billing system (tariff) in which the cost per kilowatt hour changes according to the amount of energy you use: x cents per kilowatt hour for the first so many kilowatt hours, y cents per kilowatt hour for the next so many kilowatt hours, and so on. Additionally, there may be a multiplication factor based on the changing price of fuel.
