Thermionic valve or vacuum tube technology came into its own when it was discovered that the triode valve could be used to amplify electronic signals.

As the name indicates, the triode valve or triode vacuum tube uses three electrodes, the cathode and anode as in the diode and a third electrode called a grid placed between the anode and the cathode.

The addition of the third electrode in the triode vacuum tube opens up its operation making it a considerably more functional device.

The triode valve or triode vacuum tube takes the basic concept of the diode and moves it on a significant stage further. A third electrode called a grid or more correctly a control grid is placed between the cathode and anode of the basic diode and by applying a potential to the grid, it is possible to repel or attract the electrons being emitted from the cathode and in this way affect the flow between cathode and anode of the triode vacuum tube.
