Unformatted text preview: characteristics are also shown. ..Va is the anode voltage and Vg is the Grid voltage. A tube's grid current is nearly zero as long as the grid is more negative than the cathode, and the anode current is given by 2 / 3 ) / ( a g p a V V k I where is known as the amplification factor and p k is a characteristic of the tube having units of amps per volt^3/2. (a) Defining the output conductance as a a V I / and the transconductance as 2 g a V I / , derive expressions for these. (b) Working with the characteristics above, compute numerical values of the transconductance and output conductance at Va=200 V and Vg= -0.5 Volts...
