Question

Differentiate between electrical resistance and resistivity of a conductor.

Answer 1

Electrical resistance	Resistivity
It is the property of the material due to which it opposes the flow of electricity through the conductor.	The resistivity is defined as the resistance of a material of 1 metre length and 1 square metre area of cross-section.
The SI unit of electrical resistance is the ohm.	The SI unit of resistivity is ohm-meter.
It is represented by the symbol R.	It is represented by the symbol ρ.
It depends on length, cross-sectional area of the conductor, and temperature.	It depends on the temperature and the material of the conductor.
