# What Do You Understand by the "Resistivity" of a Substance? - CBSE Class 10 - Science

ConceptFactors on Which the Resistance of a Conductor Depends

#### Question

What do you understand by the "resistivity" of a substance?

#### Solution

We know that resistance , R=(rhol)/A

So resistivity,  rho=RA/l/

When the area of cross-section, A is 1 m2 and the length of the wire, l is 1 m, resistance is equal to resistivity.

Resistivity may be defined as the resistance offered by a conductor of length 1 m and area of cross-section 1 m2.

Is there an error in this question or solution?
