Question

two bulbs one rated 100 watt at 220 V and the other 60w at 220 V are connected in series to a 220 V supply find the current through each bulb

Answer 1

by formula p=v*i
i =p/v
p1+p2=100+60=160
160/220
0.72727
=approx 0.73amphere
if you want to find supply from each bulb then dont add the power and divide it by resistance each
