Thanks lots Rude man o:) Hmm that's interesting i came across a Richardson-Dushmann law as well but it's not so similar, but that's how i get the "dJ/J=dT/T ( 2 + ((1160x1.3)/1000)". But it's differentiate with respect to the absolute temperature. Btw do u mean i could use the same formula...

% change in thermionic emission Q1. Determine the % change in thermionic emission for an oxide-coated filament of work function of 1.3eV if the temperature is decreased by 1.00% at a temperature of 2300K I'm uncertain but i used dJ/J=dT/T ( 2 + ((1160x1.3)/1000) to get a 15% change in...
