Question

hii friends .....^_^

plz follow me......

so the question is.....

a small bulb has a resistance of 2 ohm when cold. it takes up a current of 0.4A from a source of 4 v and then starts growing . calculate
1)the resistance of the bulb when it is glowing and
2)elaborate on the reason for the difference in resistance ?

^_^

Answer 1

V=IR

R=V/I

4/.4

10

So result will be 8 ohm
