Question

Fast fast answer please??

Answer 1

Answer:

resistivity is the nature of resistance.it is independent of length and area.

it's unit is ohm meter

Answer 2

Answer:

hey here is your answer

Explanation:

1. RESISTIVITY - it is a measure of resistivity power of a specified material to the flow of electric current.

FORMULA - R = p L/A

P = R A/L

Where R = resistivity

A = area of cross section

L = length of wire

[P] = ohm [m²/ m]

P = ohm.meter [S. I unit ]

2. MOLAR CONDUCTIVITY- at definite temperature the conductivity of ions in a solution containing of ions in a solution containing 1 GM mole of electrolyte is called molar conductivity.

FORMULA - Am = k × V

Am = k × 100 / m

unit - ohm-¹ cm ² mol-¹
