Schematic field electron emission measurement circuit, operating in unfavorable conditions. If high series (“ ”) and/or low parallel (“ ”) resistances exist in the circuit, then the voltage applied across the emitter, and the emission current , will not necessarily be equal to the measured voltage and current .
