Question

A car bulb connected to a 12 volt battery draws 2 A current when glowing. What is the resistance of the filament of the bulb? Will the resistance be more,same or less when the bulb is not glowing?

Answer 1

by ohm law

v= ir

12=2×r

r=6 ohms

the resistance will remain the same in all conditions

Answer 2

Answer:

v=12v

I=2A

r=?

v=iR

12v=2A×R

12v/2A=R

6=R

hope it helps u well
