Question

What do you mean by resistivity ?????​

Answer 1

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.

resistivity = resistance × area / length

Answer 2

Answer:

$\red{ \huge \boxed{resistivity}} \\ \\ \\ it \: is \: the \: measure \: of \: resistance \: of \\ \\ area \: per \: unit \: length \\ \\ \\ or \: \\ \\ the \: ratio \: of \: electric \: field \: and \: current \: \\ \\ density \: is \: known \: as \: resistivity \: of \: a \: conductor \\ \\ = \frac{e}{j}$
