Question

"Class X : Two lamps, one rated 40 W, 220 V and the other having resistance 605
Ω(ohm) 60 W, 220 V are connected in parallel combination across to a 220 V
supply. Calculate the current drawn from the supply line. "

Answer 1

Given :
Two lamps with power 40 W and 60W are conneted in parallel

Voltage=220v

Total power= 40+60=100W

Calculate current drawn:
Formula :
P=VI
I=P/V
=100/220
=5/11 A
=0.45A

∴Current drawn is 0.45A
