Let’s say you want to blink an LED. You might grab an Arduino and run the Blink sketch, or you might lace up a few components to a 555. But you needn’t go so fancy! [The Design ...

The two types of standard transistors are PNP and NPN which differs in circuit symbols. The layers of semiconductor material used to make the transistor are denoted by the letters. To keep a straight ...

Manufacturing companies, particularly those that mass-produce electronic circuits, work pretty much around bipolar junction transistors, like PNP and NPN. However, choosing between these two BJTs can ...

There was no doubt about it, point-contact transistors were fidgety. The transistors being made by Bell just didn't work the same way twice, and on top of that, they were noisy. While one lab at Bell ...

How Do Transistors Work? At its core, a transistor is an electronic gatekeeper. It controls the flow of electric current through a semiconductor material. Most transistors have three terminals, often ...

Wood isn’t usually very good at conducting electricity, but now scientists have created the first functional wooden transistor. It’s not the best, and it requires some processing, but it does work and ...
