When designing, repairing, or servicing triode valve / triode vacuum tube circuits it is very useful to have an understanding of the theory and what the different performance specifications mean.
The voltage and current relations in the triode for both anode and grid are of importance along with figures like triode amplification factor, the anode or plate resistance and the transconductance.
All of these give an understanding of the performance of a particular triode valve or triode vacuum tube.

Triode Construction
Riode tube is composed of three electrodes (Tri means three while Ode means electrodes). One of these is called cathode (filament type or indirectly heated oxide coated type), second one anode (plate) and the third one control grid. Grid is kept between cathode and anode and it is closer to cathode as compared to anode.triode valve is similar to diode with the exception that there is a grid between cathode and anode.
Control grid is composed of a fine wire mesh structure or circular helix (though grid’s structure may be in other shapes as well apart from circular helix e.g. smooth, oval, spring type or stairs like). The objective of making grid as a mesh wired tube is to allow electrons pass through it freely. Due to its mesh structure, grid does not pose any direct hurdle in the way of flow of electrons moving towards anode, however it has striking influence on the electric field created between anode and cathode, when voltage is supplied to the grid, as result, the total flow of electrons gets influenced.
Wires of different sizes are used in control grid according to designs and the electric field formed inside the tubes. Grids are usually made from Microbe, molibanium, nickel, iron, tungsten, tantalum and different alloys. The size of triodes valves depend on its power rating and purpose of its usage. They are available in different sizes due to the empty space available between its electrodes. It is to be remembered that that plate current depends on construction of grid and its spacing.
