Semiconductor Simulation
Transistor application circuit
The above simulation is based on a circuit that actually works. The transistor uses C1815(general-purpose NPN switching transistor). The resistance connected to the base is 100kΩ, and the resistance connected to the…

The principle of a transistor
Transistor There are so many switches in your computer. It is not a hand-push switch that we commonly use. It is a switch operated by electrical signals. The computer counts numbers as…
