Question

what happens to the resistance as the conductor is made thicker?​

Answer 1

Answer:

The expression for resistance is

If the conductor made thicker, the area of cross-section of the conductor increases. So, as area of cross-section increases, the resistance of conductor decreases. Thus, the resistance of conductor decreases if there is the conductor is made thicker.

Answer 2

Answer:

R

=

ρ× l/a

ρ

is resistivity of the material.

l is length of resistance.

a is area of cross-section.

If the conductor made thicker, the area of cross-section of the conductor increases.

As,

R

∝

1

a

So, as area of cross-section increases, the resistance of conductor decreases.

Thus, the resistance of conductor decreases if there is the conductor is made thicker.
