Two lamps one rated 100 wat at 220V and other 40W at 220V are connected in parallel to 220V mainsupply. Calculate the current drawn from the supply line

Expert Answer:

For combinations of devices in parallel, the total power of the devices just add up thus total power of combination will be: 100+40 =140W
thus total current drawn: I=P/V = 0.64A
