What does the voltage drop of diode and triode have to do with?

The forward voltage drop of diode and the forward voltage drop of triode emitter junction are not greatly related to the power supply and volume, but mainly related to the semiconductor material and doping concentration. In addition, the greater the current, the greater the voltage drop.

The pressure drop caused by energy loss when a fluid flows in a pipe. This energy loss is caused by the collision and exchange of momentum between fluid particles when overcoming internal friction and turbulence. It is manifested in the pressure difference before and after fluid flow, that is, pressure drop.

Triode, the full name should be semiconductor triode, also known as bipolar transistor and crystal triode. It is a semiconductor device for controlling current. Its function is to amplify weak signals into electrical signals with large amplitude. It is also used as a contactless switch. Crystal triode is one of the basic components of semiconductor. It has the function of current amplification and is the core component of electronic circuit. Triode is to make two PN junctions close to each other on a semiconductor substrate. The two PN junctions divide the whole semiconductor into three parts. The middle part is the base area, and the two sides are the emission area and collector area. The arrangement modes are PNP and NPN.
