Suppose that a wire leads into another, thinner wire of the same material that has only one-fifth the cross-sectional area. in the steady state, the number of electrons per second flowing through the thick wire must be equal to the number of electrons per second flowing through the thin wire. if the electric field in the thick wire is 1.6 × 10-2 n/c, what is the electric field in the thinner wire?
