Question

what is electrical resistivity resistivity of a material? what is its unit? Describe an experiment to study the factors on which the resistance of conducting wire depends. ​

Answer 1

Answer:

Electrical resistance is the ability of the material to oppose the flow of electrons (or electric current) when a voltage is applied between two points of the material, while conductivity is the ease with which the electrons flow through the material, and is the inverse of the resistivity.its unit is "om meter"

Explanation:

electrical resistance is a property of material which opposes flow of current

Answer 2

Answer:

electric resistivity is a property of a material that quantify how strongly it resist or conduct the flow of electric current.

Its S.I unit is ohm metre.

Resistance of a conductor depends -

1. on its length

2. on its area of cross section

3. on its nature of material
