To maintain the increased spacecharge additional DC voltage is required. The Electronic Efficiency: The performance chart also shows thenot too surprising fact that more power may be drawn from the magnetronas the voltage and current are increased. More interesting are the increaseof the over-all efficiency with voltage and the maximum through which theefficiency passes with increasing current. This variation of over-all effi-ciency, 1), is to be attributed to changes in the electronic efficiency, r]e, sincethe other factor involved in the over-all efficiency, the circuit efficiency, t7c,is essentially constant over the diagram (77 = TjeTjc)..
