CUET and UG exam CUET UG 2025 Mock Test Series Physics Current, Resistance and Electricity Resistance and Resistivity
The electrical resistivity of the material of a conductor is ρ. If the resistance and volume of the conductor is 3 Ω and 3 m3, then find the length of the conductor.
1
\( l = \frac{1}{3\sqrt{\rho}}\)
2
\( l = \frac{\sqrt{\rho}}{3}\)
3
\( l = \frac{3}{\sqrt{\rho}}\)
4
l = 3√ρ
