Analysis of a Simple Triode Amplifier Circuit:

The basic diagram of a basic triode is given below:

Fig 1:

To understand how a triode circuit would function, it is important to first understand how a triode would function. The basic elements of a triode are shown in Fig 1 above. It consists of a cathode, a plate, a heating element and a grid contained inside a bulb which has a vacuum inside.

The cathode, as the name suggests, is of -ve polarity, the plate is of positive polarity. The filament is the heating element and heats the cathode. This heating leads to the production of electrons. The grid is the electric terminal where the signal to be amplified is connected. A separate heating element ensures that the cathode does not carry the extra current required for ...
