Speaking of the Pinecil, it uses an unorthodox driving circuit – it has an NPN transistor, but its base driven through a capacitor, so that only the AC component of the driving signal gets through.

Thus the three basic bipolar transistor circuit configurations have equivalents ... There are equivalent P-channel devices, just as there are PNP and NPN bipolar transistors.

In this lesson, students build two circuits and explore how transistors ... The diagram illustrates the basic design of an NPN junction transistor. Two slices of N-type semiconductor, the emitter ...

What does "NPN" or "PNP" mean in terms of a transistor ... Typical signs of a failing transistor include a circuit that's not functioning as expected, or a device that's overheating or not powering on ...

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 ...
