Question

what is the difference between resistance and Resistivity

Expert Solution

Step 1

Resistance of a conductor is its extrinsic property which depends on dimensions of the conductor. Hence conductor of different dimensions of the same material will have different resistance. Its formula is given as follows:

$R = ρ \frac{l}{A}$

R is the resistance

l is the length of the conductor

A is the area of cross-section

$ρ$ is the resistivity of the conductor
