What is the unit of resistivity in CM?

Thus, in the metre-kilogram-second system, the unit of resistivity is ohm-metre. If lengths are measured in centimetres, resistivity may be expressed in units of ohm-centimetre.

What is SI unit of resistivity?

The SI unit of electrical resistivity is the ohm-meter (Ω⋅m).

Is resistivity and specific resistance same?

The resistivity is also known as specific resistance. The resistivity represents the resistance of the material which has specific dimensions, i.e., the material has 1-meter length and 1 square meter area of cross section.

What is resistivity mention its SI unit and how does it vary with temperature?

It is the resistance of a unit length with unit area of cross section of the material of the conductor. Resistivity The resistivity depends upon the nature of material and average relaxation time of the free electrons in the conductor. It varies with temperature also. The SI unit of resistivity is ohm-m.

How is the resistivity different from resistance of a conductor?

Furthermore, an important difference between resistance and resistivity has to do with the flow of free electrons. Also, resistance is an aspect that opposes the flowing of free electrons. In contrast, resistivity is any material’s property that tells the resistance of the material with a particular dimension.

What is the SI unit of resistance find one difference between resistance and resistivity?

What is the difference between resistance and resistivity?

Resistance	Resistivity
Its SI unit is ohm	Its SI unit is ohm meter.
It is denoted by R.	It is denoted by ρ (rho)

Is resistivity directly proportional to resistance?

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.

What is resistivity and on what factors it depends?

The resistivity of a material depends on its nature and the temperature of the conductor, but not on its shape and size. The SI unit of electrical resistivity is the ohm-meter. Hence resistivity is dependent on the temperature.

What is difference between resistance and resistivity?

Resistance is the physical property of a substance because of which it opposes the flow of current i.e. electrons. Resistivity is the physical property of a particular substance which is having particular dimensions.
