Define relaxation time or mean free time.

Define relaxation time of the free electrons drifiting in a conductor. Establish a relation between drift. Velocity and time of relaxation. Use this relation to deduce the expression for the electrical resistivity of the material.

Define relaxation time of the free electrons drifting in a conductor.How is it related to the drift velocity of free electrons? Use this relation to deduce the expression for the electrical resistivity of the material.

Define relaxation time of the free electrons drifting in conductor. How is it related to the drift velocity of free electrons? Use this relation to deduce the expression for the electrical resistivity of the material.

Write mathematical relation between mobility & drift velocity of charge carries in a conductor mobility & relaxation time (or) mean free unit.

Calculate the relaxation time and mean free path at room temperature (i.e. 27^(@)C ). If the number of free electrons per unit volume is 8.5 xx 10^(28)//m^(3) and resistivity rho = 1.7 xx 10^(8) Omega-m . Given that mass of electron = 9.1 xx 10^(-31) kg e = 1.6 xx 10^(-19)C and k = 1 .36 xx 10^(-23) JK^(-1)
