Discrimination of triode products
Discrimination of the base of the triode: According to the schematic diagram of the structure of the triode, we know that the base of the triode is the common pole of the two PN junctions in the triod

The role of the triode
The transistor has a current amplifying effect, and its essence is that the transistor can control the large change of the collector current with a small change of the base current. This is the most b

The emitter region of the triode emits electrons to the base region
The power source Ub is applied to the emitter junction through the resistor Rb, the emitter junction is forward biased, and the majority carriers (free electrons) in the emitter region continuously cr

The collector area of the triode collects electrons
Due to the large reverse voltage applied to the collector junction, the electric field force generated by this reverse voltage will prevent the electrons from the collector region from diffusing to th

Diffusion and Recombination of Electrons in the Base Region of a Triode
After the electrons enter the base region, they are first concentrated near the emitter junction, and gradually form a difference in electron concentration. Under the action of the concentration diffe

The development history of triode
On December 23, 1947, at Bell Labs in Murray Hill, New Jersey, three scientists - Dr. Bardeen, Dr. Brighton and Dr. Shockley were nervously and methodically doing experiments. They are conducting expe

Basic definition of triode
Transistor (also called transistor) is only a general term for three-pin amplifier devices in Chinese meaning. The triode we often say may be several devices. It can be seen that although they are all

triode
Triode, the full name should be semiconductor triode, also known as bipolar transistor, transistor, is a semiconductor device that controls current. Its function is to amplify the weak signal into an
