energy meter is nothing but a device.

Answer / nagaseshareddy.m

energy meter is enclosed in a glass case. Within the case
is a revolving disk which in turn rotates a series of
numbers or dials. The disk rotates as electric current
passes through the meter to measure the exact amount of
kilowatts used. The speed varies depending on how much
electricity you are using in your house. The more
electricity you use, the faster the rotation. energy
measured in kwh ( E=Pxt) it works on electro magnitic
principle.
