In this lesson, students build two circuits ... junction transistor, a three-layer sandwich of different types of semiconductor. The diagram illustrates the basic design of an NPN junction transistor.

On the other hand, checking with the datasheet for the pinout will eliminate this problem, and when drawing the schematic, the FET symbol ... driving circuit – it has an NPN transistor, but ...

This transistor switching circuit uses an npn transistor, a voltage divider (consisting of a \(5 kΩ \) resistor and thermistor) and a \(5 V\) power supply. Use the information in the table to ...
