Question

The electrical resistance of a metallic conductor is inversely proportional to its

Answer 1

Answer:

Explanation:

The resistance of a wire is directly proportional to its length and inversely proportional to its cross-sectional area. Resistance also depends on the material of the conductor. See resistivity. The resistance of a conductor, or circuit element, generally increases with increasing temperature.

Answer 2

Electrical resistance is inversely proportional to the area of cross section.

Explanation:

The electrical resistance of a metallic conductor is given by the formula as follows :

$R=\rho\dfrac{l}{A}$

Here,

$\rho$ is the resistivity of the material

l is the length of the wire

A is the area of cross section of the wire

So, from the above formula, it is clear that the resistance of a conductor is directly proportional to the length of the wire and inversely proportional to the area of cross section.
