A transistor is a tiny device that either switches electric current on and off or amplifies an electric current. The original transistors were small cylinders, a bit larger than a pencil eraser.

But they have a rich history, going back through the silicon era to germanium junction transistors, and thence to the original devices. if you’ve ever looked at the symbol for a transistor and ...
