A 2 – core copper cable supplies a single-phase purely resistive load consisting of three 3W lamps each, and a single lamp of 9W all at 240V and 0.78 PF. The cable runs for 40m and each conductor has cross sectional area of 35mm2. Calculate; d) Voltage drop at the load end. e) I2R losses in the cable f) The MCB rating from the DB if the aggregate load is independently control. Take 0.017 copper m  = −
