Here’s a simple FET circuit that lets you switch ... Speaking of the Pinecil, it uses an unorthodox driving circuit – it has an NPN transistor, but its base driven through a capacitor, so ...

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.

There is another family of transistors which have analogous circuit configurations to their ... There are equivalent P-channel devices, just as there are PNP and NPN bipolar transistors.

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 ...
