The gap between two plane plates of a capacitor equal to d is filled with a gas. One of the plates emits n subscript 0 end subscript electrons per second, which moving in an electric field, ionize gas molecules, this way each electron produces alpha new electrons (and ions) along a unit length of its path. Find the electronic current at the opposite plate, neglecting the ionization of gas molecules by formed ions. Take charge on an electron as e
