Question

what do you mean by resistivity answer in 10000 words ?

Answer 1

Heya........

here is ur answer.......

Resistivity is a measure of the resistance of a given size of a specific material to electrical conduction. ... Materials that conduct electrical current easily are called conductors and have a low resistivity.

dear we cant answer.......in more than 5000 words..........

its the word limit.......

hope it helps.........

plzz mark me as brainliest my dear !!!!!!!!!

Answer 2

can't answer in 10000 words bcoz the word limit is 5000 words but can explain it in a nice way!!!

RESISTIVITY

a measure of the resisting power of a specified material to the flow of an electric current.

FORMULA

The SI unit of electrical resistivity is the ohm⋅metre (Ω⋅m). It is commonly represented by the Greek letter ρ, rho. Although the SI resistivity unit, the ohms metre is generally used, sometimes figures will be seen described in terms of ohms centimetres, Ω⋅cm.

HOW TO CALCULATE

To calculate the resistance R of a wire, we need to know three things:

its length – the longer the wire, the greater its resistance.

its cross-sectional area A – the greater the area, the less its resistance.

the resistivity of the material r – the greater the resistivity, the greater its resistance.

SYMBOL

A low resistivity indicates a material that readily allows the flow of electric current. Resistivity is commonly represented by the Greek letter ρ (rho). The SI unit of electrical resistivity is the ohm-metre (Ω⋅m).
