The motion of charges in an ohmic material can be described by a drift velocity v, that is directly proportional to the electric field Ē in the material. But Coulomb's law F = qË implies that charges in an electric field experience a force and thus should be accelerating. How does an electric field lead to a constant drift velocity for charges in these materials?
