DESCRIPTION
Task id14247
Let us assume that the anode and cathode are plane-parallel plates located at a distance d = 1 cm from each other, and the space charge does not limit the magnitude of the current. The cathode temperature is T = 2000 K. What potential difference V must be applied between the cathode and anode so that the emission current increases by 10% compared to the Richardson-Deshman formula?
