Specific resistance, also known as resistivity, is a fundamental property of materials that quantifies their ability to resist the flow of electric current. Here’s a more detailed overview:

• Specific Resistance (Resistivity): It is defined as the resistance of a uniform material with a unit length and unit cross-sectional area when a constant voltage is applied across it. The formula for resistivity (ρ) is given by:

$\rho = R \cdot \frac{A}{L}$

Where:
R  = Resistance of the material (in ohms, Ω)
A = Cross-sectional area (in square meters, m²)
L = Length of the material (in meters, m)
