Two lamps one rated 100 W; 220 V and the other 50 W; 220 V, are connected in parallel to electric mains supply. Find the current drawn by two bulbs from the line, if the supply voltage is 220 V |

Answer» Power of one lamp = 100 W Power of second lamp = 60 W Total power consumed in the circuit = 100 + 60 = 160 W Voltage of the main supply = 220 V P=VI I(Current) =P/V=160/220=0.727 A |
