Question

if a wire has uniform area then it is stretched will its area change ?​

Answer 1

Answer:

Assuming ideal conditions with no distortions in the process that would alter the resistivity of the wire being stretched, this becomes a relatively simple arithmetic calculation for sixth grade algebra students. Realizing that the amount of wire does not change and assuming the shape of the wire still takes on the shape of a right circular cylinder, then the volume of the wire can be determined by V = A x L where V is the volume, A is the cross sectional area, and L is the length of the wire. This relationship tells us that the volume of a right circular is directly proportional to both the area of the cylinder and the length of the cylinder. This means that if we double the length and not change the cross sectional area the volume doubles, and if we double the length and halve the area the volume will remain the same.
