(a) Solve the Drude equation for an electron in a metal sample that is in a constant electric field E₀. Leave the integration constants unknown.

(b) Suppose that at the time t₀ = 0 we disconnected the electric field. What is the dependence of drift velocity on time?

(c) What is the solution for the drift velocity v_d in part (a) for t >> τ? Suppose that the drift velocities of all electrons are equal to what is the current density j = −env_d? Derive Ohm's law and DC electrical conductivity from this relation.

The result:

(b) vd=p0/m x e-t/τ
