Two lamps, one rated 100 W at 220 *V*, and the other 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*?

*V*, and the other 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*?

Both the bulbs are connected in parallel. Therefore, potential difference across each of them will be 220 *V*, because no division of voltage occurs in a parallel circuit.

Current drawn by the bulb of rating 100 W is given by,Power = Voltage x Current

Current = Power/Voltage = 60/220 A

Hence, current drawn from the line = 100/220 + 60/220 = 0.727 A
