A single phase energy meter which is designed to make 120 revolution for one unit of energy. It takes N number of revolution when connected a load which carrying a current of 35A at 220 V and 0.55 power factor for one hour. If the energy meter actually makes 490 revolution, then what would be the percentage error, does the meter is moving fast or slow.
