A 230 V, single phase energymeter has a constant load of 4 A passing through it for 6 hours at unity p.f. if the meter disc makes 2208 revolutions, during this period, what is the meter constant in revolutions/ kWh. Calculate the power factor of the load if the number of revolutions made by the meter are 1472 when operating at 230 V, 5-A for 4 hours.
