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»

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
