Direct permeability coefficient of triode with flat electrodes¶
The coefficient of direct permeability of the grid characterizes its shielding effect and shows how much the electrostatic field of the anode is weaker than the grid field affects the cathode area. There is no general formula for this coefficient for an arbitrary electrode configuration, but there are formulas for special cases. One such case is a triode with flat electrodes.
