Question

hey...guys plzz explain it..

if an electric bulb connected to 220v line draws an electric current of 0.5 A then what will be the resistance of filament of the bulb?

Answer 1

$\huge\red{heya!!!!}$

according to ohm's law

V = I R

R = V/I

R= 220/0.5

R= 2200/5

R= 440 OHM

THANKS

Answer 2

V (voltage)= 220v
I (current) =0.5A
p (power)=VI
220*0.5=110w answer
hope haplful
plz mark brilliant
