Question

The resistance of a conductor of length X is r. if it's area of cross-section is a, what is its resistivity? what is its unite?

Answer 1

Resistivity remain same as it is a property of material .I ts unit will be ohm m

Answer 2

Answer:

$e(resistivity) = \frac{length(l)}{resistance(r )\times \: area \: of \: crosssection } \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{x}{r \times a}$

unit of resistivity is ohm *meter

Resistivity is x/ra
