Answer 1

Answer

Resistivity definition:

The resistivity of a substance is the resistance of a cube of that substance having edges of unit length, with the understanding that the current flows normal to opposite faces and is distributed uniformly over them.

Answer 2

Answer:

Resistivity definition:

The resistivity of a substance is the resistance of a cube of that substance having edges of unit length.

With the understanding that the current flows normal to opposite faces and is distributed uniformly over them.

The SI unit of electrical resistivity is the ohm⋅metre (Ω⋅m).
