Question

If the cross-sectional area of a wire is decreased while all other factors remain the same, how will the resistance change?

A.
It will increase.
B.
It will decrease.
C.
It will go to zero.
D.
The cross-sectional area does not affect resistance.

Answer 1

Answer:

A. It will increase.

Explanation:

Resistance is directly proportional to the area of cross section.....

ALL THE BEST

Answer 2

Explanation:

It will increase.

because,

On decreasing the cross-sectional area of a conductor, less current will flow through the conductor.

and

resistance is inversely proportional to cross section area.
