3) In a vacuum diode electrons are emitted from a hot grounded cathode (V-0) and they are accelerated towards the anode at potential Vo (see Griffiths, prob.2.48). The clouds of emitted electrons build up until they reduce the electric field at the cathode to zero. From then on a steady current I flows between the plates. Let the anode and cathode be much larger than the distance d between them, so that the potential φ, electron density ρ and electron...
