Silicon Carbide Tubes - An Overview
usual values of gm for a small-signal vacuum tube are one to 10 millisiemens. It is probably the a few 'constants' of the vacuum tube, another two becoming boron carbide ceramic plates its obtain μ and plate resistance Rp or Ra. The Van der Bijl equation defines their partnership as follows: g m = μ R p \displaystyle g_ m = \mu \around R_ p subs
