The number of revolutions made by the energy meter per kilowatt-hour is known as the meter constant of an energy meter.
It is represented by k.
The energy consumed in time 't' is given by:
For t = 1 hr
where, V = Voltage
I = Current
cosϕ = Power factor
Calculation
Given, Power consumption = 2300 W = 2.3 kW
Time = 1 hour
Energy consumed = 2.3 kWh
Number of revolutions = 230
k = 100 rev/kWh
