MERALCO Electrician has a 25 kW series generator used in street lighting has an efficiency of 85 % when operating at rated load. If the stray power loss is 20 % of the full load loss, calculate the efficiency of the generator when delivering a load of 15 kW, assuming that the stray power loss is substantially constant and the other losses vary as the square of the load.
