We have derived the the probability current in 1-dimension

We have derived the the probability current in ldimcnsion n #811! _ are Eli-93$) = g: 5 83: ~11). Evaluate it for the wave function (plane wave] mm) = Amie: Em, and express it in terms of velocity 'u of the particle. Compare this result in quantum mechanics with the expression for the charge current density in electromagnetism int) =IN, where p is the charge density and v is the charge velocity. Do you see the analogy
