# How Does A Watt Hour Meter Work?

If you are a science buff, you may wonder how a watt hour meter works. Watt hour or electric meters measure the amount of power a building uses in kilowatt hours. Most watt hour meters are powered by a spinning metal disk. Incoming electricity passes by the disk in coils, which generates a weak magnetic field that pulls on the disk, causing it to spin. The more energy that is used, the stronger the field, and the faster the disk spins.
Reference:
All watt meters are enclosed in a glass case. There is a revolving disk which rotates the numbers and dials. The disk rotates as electric currents passes through the meter. It measures the exact amount of kilowatts being used. You can find more information at www.rp-l.com
A watt hour meter is a device that tells you exactly how much electricity is being used by whatever is plugged into it. Plug whatever you are monitoring into the watt hour meter, then plug the meter into an outlet. The meter immediately displays how much electricity the device is using.
Watt hour meters use small, rotating disks to record the usage of power. As the disks spin, the meter tracks how many kilowatt hours are used. Also called electrical meters, the first disk records every killowatt hour used, the second disk every 10 killowatt hour, and so on for 100, 1, 000 and 10, 000.
