The Characteristic Curves of the Triode

A method is described by which the entire static characteristic curves for the plate current of a power triode can be deduced from one experimentally determined curve. This experimental curve can be obtained at low power without danger of overheating the tube. Using the same procedure, the grid-current curves and the total space-current curves can be determined. A new log-log chart is described on which the static characteristic curves of a triode are presented by means of straight lines, and two curves giving the division of space current between the grid and plate.
