Find the resistivity of a conductor having length 2m area of cross sec

1.	Find the resistivity of a conductor having length 2m area of cross section 1.4 x 10 raise to the power -6 and resistance of 0.04 ohm.
Answer» R = \(\frac{\rho l}A\) \(\rho = \frac{RA}l\) \(\rho=\frac{0.04\times1.4\times10^{-6}}2\) \(\rho = \) 0.028 x 10^-6 \(\Omega\)m

Find the resistivity of a conductor having length 2m area of cross section 1.4 x 10 raise to the power -6 and resistance of 0.04 ohm.

Answer»

R = \(\frac{\rho l}A\)

\(\rho = \frac{RA}l\)

\(\rho=\frac{0.04\times1.4\times10^{-6}}2\)

\(\rho = \) 0.028 x 10^-6 \(\Omega\)m
