A particular conductor has 3.0 × 10^27 mobile electrons per cubic meter. The material is in the shape of a cylinder of length 6.
irina1246 [14]

Answer:

Explanation:

Given

Length of cylinder L=6 cm

diameter of cylinder d=1 cm

Area of cross-section A=\frac{\pi\times d^2}{4}

A=\frac{\pi \times 10^{-4}}{4}=7.855\times 10^{-5} m^2

Emf =2.5 V

current I=5 mA

Resistance=\frac{V}{I}=\frac{2.5}{5\times 10^{-3}}

R=500 \Omega

R is also given by

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

where \rho =resistivity

\rho =\frac{RA}{L}=\frac{500\times 7.85\times 10^{-3}}{6}

\rho =0.654 \Omega -m
