Two lamps, one rated 100 W at 220 V, and the other rated 60 W at 220 V, are connected in parallel to electric mains supply. What current is drawn from the line if the supply voltage is 220 V?

P1 = 100 w            P2 = 60 W            P = P1 + P2 = 160 W            V = 220 V            I = ? Using P =IV or I = P/V            = 160/220 = 0.73 A
