Your electric meter records electricity usage in kilowatt-hours. In simple terms, 1 kilowatt hour = 1,000 watt-hours. For example, if you turn on a 100-watt light bulb for 10 hours, the energy usage is calculated as 100 watts x 10 = 1,000 watts (or 1 kilowatt hour).
How an electric meter reads power usage?
Electricity meters operate by continuously measuring the instantaneous voltage (volts) and current (amperes) to give energy used (in joules, kilowatt-hours etc.). Meters for smaller services (such as small residential customers) can be connected directly in-line between source and customer.
Which meter is used to consume energy?
Electric meter or energy meter is a device that measures the amount of electrical energy consumed. The most common unit of measurement on the electricity measurement is the kilowatt hour [kWh], which is equal to the amount of energy used by a load of one kilowatt hour over a period of one hour.

What is the difference between power meter and energy meter?
The Wattmeter measures the electrical power flows in the circuit, while the energy meter measures the total electrical energy consumed by the electrical load.
Do electric meters measure real or apparent power?
The digital meter measures voltage and current directly, and over the course of many samples can measure and accumulate voltage and current readings, as well as calculate the apparent power used. Real power is calculated by multiplying the voltage and current at any instant (one pair of samples).
How do smart meters measure electricity?
A Smart Meter works by measuring the electrical current flow and voltage at regular intervals and then adding this up to calculate the power used in a half-hour period. Similarly, for gas the flow is measured at regular intervals. This information can be sent to your In Home Display and to your supplier.
