Question

Define the resistance and resistivity

Answer 1

The resistance of an object (i.e., a resistor ) depends on its shape and the material of which it is composed.Resistivity ρ is an intrinsic property of a material and directly proportional to the total resistance R, an extrinsic quantity that depends on the length and cross-sectional area of a resistor.

Answer 2

$\textbf{Your answers is --}$

$\textbf{Resistance =>}$ Resistance the the property of the conductor which can oppose the flow of current in conductor .

Resistance of conductor is depend upon

● Lengthy

● Area of cross section

● Temperature

● Material of conductor

$\textbf{Resistivity => }$ It is the resistance of a conductor whose length is one meter and area of cross section is one sq-meter.

Resistivity of conductor is depend upon

● Temperature

● Material of conductor
