Question

b) When an electric bulb is connected to a 220V mains a current of 0.5 flows through  the bulb. Find the resistance of the bulb ?

$\fbox\blue{A}\fbox\red{N}\fbox\blue{S}\fbox\red{W}\fbox\blue{E}\fbox\red{R}$

from the ohm's law.

I = V/R

given that V = 220 and I = 0.5

R = V / I --> 220 / 0.5 --> 440 ohm

Hope it helps you
