If n, e, tau , m, are representing electron density charge, relaxation time and mass of an electron respectively then the resistance of wire of length 1 and cross sectional area A is given by

The resistance will be least in a wire with length, cross-section area respectively,

If n ,e,m and tau are free electron density in conductor , charge of electron, mass of electron and relaxation time of free electrons , then resistivity rho of the conductor can be expressed as

If the free electron density be n and relaxation time be tau , the electrical conductivity of a conductor may be expressed as

If in a conductor number density of electrons is 8.5xx10^(28) average relaxation time 25 femtosecond mass of electron being 9.1xx10^(-31) kg, the resistivity would be of the order.

If two conducting wires Aand B of same dimensions have electron density ratio 1: 3 . If their relaxation time is same then the ratio of resistance of A to resistance of B is
