Question

what is electrical resistivity? what is its unit? describe the factors depending on conductors.​

Answer 1

Answer:

If I is the length of the conductor, A its area of the crosssection and R its total resistance then, Where P is a constant of proportionality and is called the electrical resistivity of the material of the conductor. The SI unit of resistivity is Ohm meter.

Answer 2

Explanation:

Obstruction offered to the flow of current is called resistance.The resistance at a specific point is called resistivity.Its S.I unit is ohm meter

Factors,

1.Temperature

2.Nature of conductor

3.Thickness of wire

4.Length of wire(conductor)

5.Area of cross section
