Specific resistance of a wire depends upon--

a)Length.

b)Cross section.

c)mass

d)None.

Specific Resistance depends upon the material of the conducting substance.
Although,
The ability of any conductor in an electrical circuit to pass current is judged by its electrical RESISTANCE. Resistance is the ability to OPPOSE the flow of electric current. The greater the value of resistance of any conductor, the less current will flow. The resistance of a conductor depends mainly on three things;

The LENGTH of the conductor.

The CROSS SECTIONAL AREA of the conductor.

The MATERIAL of which the conductor is made.

Because the resistance is greater in longer conductors than in shorter ones, then;

RESISTANCE IS PROPORTIONAL TO LENGTH

Which is written as; R ∝ L (∝ means proportional to...)

Also, because resistance is less in conductors with a large cross sectional area;

RESISTANCE IS INVERSELY PROPORTIONAL TO CROSS SECTIONAL AREA

Which is written as; R ∝ 1/A (or R ∝ A-1)

Dear Student

Specific resistance of a wire is an intrinsic property of the material of wire.
So it depends only on the material of the wire but not on the dimensions of the wire.

I hope this answer will help you.
