Question

hey guys!!❤️❤️

Please answer this question ⤵️⤵️

A small bulb has a resistance of 2 ohm when cold.It takes up a current of 0.4 a from a source of 4v and then starts flowing calculate

i) the resistance of the bulb when it is glowing and

ii) elaborate on the reason for the difference in resistance?

​

Answer 1

Answer:

R = V/I

R=4/0.4

R=10 ohms

i think the difference is because of using the bulb means at first it will be cold after it will become hot

Answer 2

Answer:

10 omh

Explanation:

r =4/0.4

i think this is your answer
