Question

How does the resistance of wire change when its length is tripled?

Answer 1

Answer:

The resistance of a wire is inversely proportional to its area and directly proportional to its length. SO, 1) When the length is tripled then resistance will also become three times. 2) If the diameter gets tripled then its resistance will become one ninth of the initial reistance.

i hope this will help uh

Answer 2

Answer:

The resistance of a wire is inversely proportional to its area and directly proportional to its length . So when the length is tripled then the resistance will also become three times and if the diameter gets tripled then it's resistance will become one ninth of the initial resistance.

thank u I hope it will help u
