Question

what are the factors which influence
the resistivity of a wire
​

Answer 1

Answer:

the resistivity of a wire is influenced by length,area, resistance, temperature of the conductor

Explanation:

as rho(resistivity)=RA/l

R=resistance

A=area

l=length

it also depends on temperature

Answer 2

Explanation:

The resistivity of the wire can be find out by using the definition of the resistance. The resistance of the wire is given by :

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

Where

$\rho$ is the resistivity of a wire

l is the length of the wire

A is the are of cross section

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

The resistivity of the wire also depends on the temperature of surrounding. So, it depends on length, area and the resistance of the wire.
