Question

Two tungsten bulbs of power 50 W and 60 W work on 220 V potential difference. If they are
connected in parallel, how much current will flow in the main conductor?
​

Answer 1

$\huge{\bigstar{\underline{\mathfrak{Answer}}}}$

P1 = 50 W

R1 = V^2 / P1 = 220^2/50

= 4840 / 5 Ohm

P2 = 60 W

R2 = V2 /P2 = 220^2/60

= 4840/6
