The Lumped Voltage

Author: J.B. Hoag

From the equation for μ, it can be seen that a voltage e_g applied to the grid can be replaced by an equivalent change of e_p = μe_g volts in the plate battery. Hence the combined effect of changes of both the grid and the plate voltages upon the electron stream can be summarized as a single or lumped voltage e_l, whose equation is as follows:
