+//Caption: Resistivity of Cu
+//Example3.5:The resistivity of metal is given by p=1/nqu, where n is number of electrons per cubic meter, u is mobility ,a nd q is electronic charge. Determine the resistivit of copper at room temperature. Given n=8.5*10^28 per cubic meter, u=3.2*10^-3 m^2/V-sec, at room temperature.
+//Solution:
+q=1.6*10^-19;
+n=8.5*10^28;
+u=3.2*10^-3;
+p=1/(n*q*u);
