Ok, so even after doing transistor theory at uni, this guy explains transistor switching SO much clearer than was taught to me. Great video. Much of the DC stuff makes so much more sense.

Transistors are tiny ... unless we have some means of triggering a switch with a signal from another switch. Here’s a relay circuit that ... PNP transistors and n-channel transistors ...

There are numerous differences between NPN and PNP transistors, and even though both are bipolar junction transistors, the direction of current flow is the name of the game.

When a weaker light beam courses through the second optical line, the ring heats up and swells, interfering with the main beam and switching off the transistor. This switch can flip on and off up ...
