How is consumption of electricity measured by an electric meters?

Your annual electricity consumption is measured directly on the meter. This counts the number of kilowatt hours (one of the units used to measure energy) delivered to you. Each time your meter is read, the difference between the reading displayed by the meter and that of the previous year is calculated.

How do electric companies measure energy consumption?

A Watthour (Wh) is equal to the energy of one Watt steadily supplied to, or taken from, an electric circuit for one hour. The amount of electricity that a power plant generates or an electric utility customer uses is typically measured in kilowatthours (kWh). One kWh is one kilowatt generated or consumed for one hour.

How is electrical consumption calculated?

To calculate power consumption of any appliance, you have to multiply it’s wattage by the number of hours it is being used (operational hours). For example, a 1000 watt electric iron running for one hour will consume (1000 watt X 1 hour) 1000 watt hour or 1 kilowatt hour (kWh) of electricity.

How is meter reading measured?

When reading an electric meter, read and write down the numbers as shown on the dials from right to left. When the pointer is directly on a number, look at the dial to the right. If it has passed zero, use the next higher number. If it has not passed zero, use the lower number.

How is electricity meter measured in units?

Just like the odometer on your vehicle that shows the actual distance travelled by the vehicle, electricity meter shows the amount of electricity that is used. So a 100-Watt bulb if kept on for 10 hours will consume: 100 x 10 = 1000 Watt-Hour = 1 Kilowatt-Hour (kWH) = 1 units (on your meter).

Is electricity measured in kWh?

A kilowatt hour (kWh) is a measure of how much energy you’re using per hour, whilst a kW is a measure of power. kW stands for kilowatt, a universal standard for measuring electricity. So, one kilowatt equals 1,000 watts. Your electricity provider charges by how much electricity you use per kilowatt hour (kWh).
