Question:
SI unit of \( \rho \) (rho) is:
SI unit of \( \rho \) (rho) is:
Show Hint
Resistivity depends on the material and is measured in \( \Omega \, \text{m} \).
Updated On: Mar 5, 2025
- \( \Omega \, \text{m} \)
\( \text{Ohm} \text{ m}^{-1} \)
\( \text{Ohm}^{-1} \)
\( \text{cm}^{-1} \)
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
The SI unit of resistivity (\( \rho \)) is \( \Omega \, \text{m} \), which is derived from:
\[
\rho = R \cdot \frac{A}{l},
\]
where \( R \) is resistance, \( A \) is cross-sectional area, and \( l \) is length.
