Question

A wire is stretched double it’s length and area is halved find out it’s new resistance

Answer 1

Answer:

As the length of the wire gets doubled, the cross-sectional area will become half of its previous value because the volume of wire remains constant. Hence, we can see that the new resistance is four times the previous resistance.

Answer 2

Answer:

FOUR TIMES

Explanation:

As the length of wire gets doubled, the cross-sectional area will become half of its previous value because volume of wire remains constant. Hence, we can see that the new resistance is four times the previous resistance.
