Question

What are the factors on which resistance of a conductor depends?

Answer 1

Resistance can be defined as

$R\propto \frac{l}{A}$

$\Rightarrow R=\rho \frac{l}{A}$

where $\rho$= specific resistance or resistivity;

$l$ = length of the wire; and

$A$= cross-sectional area of the wire.

Hence resistance of any conductor depends on its specific resistance, temperature, and dimension of the conductor.
