Question

Which has more resistance:- (a) A bulb at room temperature not glowing. (b) A glowing bulb. Give reason for it?​

Answer 1

Answer:

A Glowing Bulb

Explanation:

The resistance of the bulb is much less when it is not glowing because resistance is directly proportional to potential difference by current . if the bulb is not glowing it means that the current is not flowing and so it has very less potential difference .

(b) A glowing bulb

I don't know the reason
