Question

What change in resistance if the diameter is triple

Answer 1

Answer:

My dear friend it is not triple , it is tripled ✌

And ur answer is here, since 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.
