Question

A property unique to a conducting substance that determines its resistance is called

Answer 1

Electrical Resistivity

Step-by-step explanation:

As we know that all different type of conductors has its different unique resistivity due to which all conductors will show different resistance for same shape and size.

As we know that the resistance of a conductor is given as

`R = \rho(L)/(A)`

here we know

`\rho` = resistivity

L = length of conductor

A = crossectional area of conductor

so here for all conductors the resistivity is unique property due to which all will show different resistance

Answer 2

It is called "electric resistivity".
Resistivity is a property of every substance that specifies how strongly that material opposes to the flow of electric current through it.
The resistance of a piece of wire of length L and cross-sectional area A is related to the resistivity of the material,
`\rho`, by the formula

`R= (\rho L)/(A)`
