Question

Which of the following can effect the resistance of a wire?

I. the length of a wire
II. the thickness of a wire
III. the temperature of a wire




II and III
I and III
I and II
I, II, and III

Answer 1

I, II AND III

Beacaus resistance depend on length, thickness and temperature of wire

If length,temperature increases then resistance will increase but if thickness increase then resistance will decreases
