Transfer and Plate Characteristics of a Triode

Author: E.E. Kimberly

In Fig. 27-10 is shown a family of curves, known as mutual or transfer characteristics, drawn for various plate voltages on a 6C5 triode. Inasmuch as the negative grid portions of the characteristics are of importance, only those portions are shown. Another set of characteristics, known as plate characteristics, is shown in Fig. 27-11 for a 6C5 triode. Fig. 27-10 and Fig. 27-11 are placed close to each other for convenience in further development. From these curves it is possible to predict the performance of a triode in a circuit. In Fig. 27-12 it is seen how a small negative grid bias voltage can be used to control the plate current produced by a large plate voltage. 5.5 volts peak-to-peak grid input 110 volts peak-to-peak plate output
