Question

two lamps one rated 100 watt at 220 volt and other at 40 watt at 220 volt are connected in parallel to 220 volt main supply calculate the current drawn from the supply line​

Answer 1

Answer:

First lamp

p=100w

V=220

p=vi

100=220i

I=100/220=5/11

second lamp

p=40w

v=220

I=40/220=2/11

total current =5/11+2/11=7/11 Ampere
