The best Side of tungsten tubes
regular values of gm for a small-signal vacuum tube are 1 to ten millisiemens. It is probably the boron carbide ceramic plates 3 'constants' of a vacuum tube, the opposite two being its achieve μ and plate resistance Rp or Ra. The Van der Bijl equation defines their relationship as follows: g m = μ R p \displaystyle g_ m = \mu \more than R_ p Th
