There are three electrodes: cathode (filament) grid and anode.
The "third" will be the one you do not already know the name of.
A crystal triode is the old term for transistor. Crystal diodes were well established by the time transistors were invented, so using vacuum tube terminology, the logical name for a diode whose current could be controlled by a third element was "crystal triode".
A Grid Controlled X-ray Tube is a triode in which a third electrode is introduced between the Anode and Cathode. This electrode is normally neutral so the x-ray production can take place. However, one can decide when to cut the exposure by introducing negative charge on this. This will then stop (repel) the electron from reaching the Anode and x-ray production is stopped. Therefore, the elecrode with a negative charge can as a timer or if chrge is given intermittently, it acts as a device to have flouroscopy in pulses.
A thryistor is a four-layered semiconductor rectifier in which the flow of current between two electrodes is triggered by a signal at a third electrode. Hope I helped! :)
one third is called a...................... a .........torrent.
third parties are also called minor parties
altru building sucka! ---------- altru building, floor ten where Isaac is in another room with scientists. In the room there's 2 Electrode and an Electabuzz. This is the first room you see when you get on the 10th floor so enter the door and BAM! :) I hope this helped more than the first person's. *points at third word*
