Thermionic emission is possible when the electron energy is higher than 9 eV for the work function of 4 eV. The electrons occupying a lower energy state than that of vacuum lead to tunneling into vacuum by the electric field, which causes field emission.

Webb13 nov. 2012 · Power efficiency formula η = Pout / Pin For example, the efficiency of a converter that provides 500W of output power (Pout) and requires 625W for the input power (Pin), would be 80% (500W/625W=0.80). In this case, the input power exceeds the output power by 125W or 20%, which is lost/wasted power. WebbView the profiles of professionals named "Adam Khreis" on LinkedIn.
