Answer 2

⭕️Resistivity is the measure of a material’s ability to oppose the flow of current .

⭕️ Resistivity of a conductor is a property of the material of the conductor.

⭕️Unit of resistivity is Ohm meter, (Ω m)

⭕️Resistivity of the material of the conductor changes with temperature.

⭕For example ️resistivity of copper is 1.7 × 10^-8 Ω m at room temperature.

⭕Remember ️ there's nothing as resistivity of a circuit.

➖ resistivity (ρ)
➖resistance (R) of a conductor of
➖length (L) and
➖ area (A).
