If the cross-sectional area of a wire is decreased while all other factors remain the same, how will the resistance change?
Nataly [62]

Answer:

A. It will increase

L is the length of the wire,

and A is the cross-sectional area.

If A decreases, while ρ and L stay the same, then R will increase.
