The resistivity offered by a cube of a substance having side of 1 when current passes through perpendicular to the opposite faces is called its resistivity.

The resistivity of a conductor depends upon its nature , length and area of cross section.

It is found resistivity of a conductor is indirectly proportional to the length and depends to the the cross section.

R ∝ L - (i)

R ∝ 1/A - (ii)

From (i)and (ii) :-

R ∝ L/A

R = ρ (L/A)

  • → ρ = Rho (Resistivity constant)
  • → R = Resistivity
  • → L = Length of conductor
  • → A = Area of cross - section

Explanation:

ResistivityinPhysics:

The resistivity offered by a cube of a substance having side of 1 when current passes through perpendicular to the opposite faces is called its resistivity.

The resistivity of a conductor depends upon its nature , length and area of cross section.

It is found resistivity of a conductor is indirectly proportional to the length and depends to the the cross section.

DerivationofResistivity:

R ∝ L - (i)

R ∝ 1/A - (ii)

From (i)and (ii) :-

R ∝ L/A

R = ρ (L/A)

→ ρ = Rho (Resistivity constant)

→ R = Resistivity

→ L = Length of conductor

→ A = Area of cross - section
