How does a transistor switch signals so fast?
Transistors are tiny components that can turn electrical signals on and off at incredible speeds. In this video, you'll learn ...
In the early days, PNP bipolar transistors were common, but the bulk of circuits you see today use NPN transistors. As [Aaron Danner] points out, many people think PNP transistors are “backward” but ...
