The gas between the capacitor plates separated by a distance `d` is unifromly ionized by ultraviolet radiation so that `n_(1)` electrons per unit volume per second are formed. These electrons moving in the electric field of the capacitor ioinze gas molecules , each electrons producing `alpha` new electrons (and ion) per unti length of its path.Neglecting teh ionization by ions, find the electronic current density at the plate possessing a higher potential.
