Demonstration Triode



The power is turned on with the switch in the line cord and the plate, grid, and filament are individually adjustable with the knobs so labeled. Demonstrate the electrons flowing from the filament to the plate (it is coated with phosphor so it glows when the electrons hit it) and the action of the grid in controlling the flow of electrons to the plate.


Comments

This device may be placed out for the students to look at before and after class. It is too small to demonstrate for a full lecture hall.
