Transistors work by using a small amount of electrical current to control ... Within these categories, there are further subdivisions such as NPN and PNP BJTs and N-Channel and P-Channel MOSFETs.

The diagram illustrates the basic design of an NPN junction transistor ... the current flowing from the transistor’s collector to the emitter—its output. 1. Work in groups of three or four.

The first transistor was about half an inch high. That's mammoth by today's standards, when 7 million transistors can fit on a single computer chip. It was nevertheless an amazing piece of technology.

If you ever work with a circuit that controls a decent ... can’t handle the high-side voltage on its pins, you can add a NPN transistor section as shown – this inverts the logic, making ...

This 2-bit adder was a lot of work to build. It uses a total of thirty ... and taking advantage of the fact that there’s an NPN transistor built into it. [cpu86] did use some PNP transistors ...

A transistor is a key component in electronics, often used as a switch or to amplify a signal from a sensor. NPN (negative-positive-negative) transistors are the most used transistor. An ...
