Review Part A Recall that the density J of current flowing through a material can be written in terms of microscopic properties of the material: j = nqva, where in is the density of current carriers, q is the charge of one current carrier, Part B and Ud is the drift velocity of a current carrier. In a metal, the current carriers are electrons. Part C Recall that the conductivity of of a substance is defined by the relation J = .E and that the resistivity p is the inverse of the conductivity: p = 1/. Give an expression for p in terms of microscopic properties of a metal. Use ge for the charge on the electron. Express your answer in terms of EF, m, ge, d, E, and n. View Available Hint(s) AEd FOE ?
