define the term ohm meter
Asked by singhchander260 | 18 Nov, 2020, 08:03: PM
Ohm-meter is the unit of resistivity

Resistance R of conductor is directly proportional to length L of conductor ,  R  L
Resistance R of conductor is inversely proportional to crosssection area A of conductor ,  R  1/A

Hence we get Resistance R = ρ × ( L / A )

where constant ρ is resistivity of material of  conductor

Unit of R = ohm ( Ω )

since unit of lenth is meter and that of area is square meter , we get unit of resistance as ohm-meter
