The formula to calculate the Bulk Resistivity (ρ) is:
\[ \rho = R \times \left(\frac{A}{L}\right) \]
Where:
Bulk resistivity, often simply referred to as resistivity, is a fundamental property that quantifies how strongly a given material opposes the flow of electric current. It is the electrical resistance of a unit length and unit cross-sectional area of the material. The lower the resistivity, the more readily the material allows the movement of electric charge. Resistivity is commonly used to compare the intrinsic electrical properties of different materials, and it plays a crucial role in the design and analysis of electrical and electronic systems.
Let's assume the following values:
Using the formula to calculate the Bulk Resistivity:
\[ \rho = 10 \times \left(\frac{0.001}{2}\right) = 10 \times 0.0005 = 0.005 \text{ Ω·m} \]
The Bulk Resistivity is 0.005 Ω·m.
