transistor explained for dummies
Here are a few additional points to ponder concerning transistors: In an NPN transistor, the emitter is the negative side of the transistor. The collector and base are the positive sides. In a PNP transistor, the emitter is the positive side of the transistor. The collector and base are the negative sides.Most circuits that you can build with an NPN transistor can also be built with a PNP transistor. But if you do, you must remember to flip the power connections.n a PNP transistor, the emitter is the positive side of the transistor. The collector and base are the negative sides.
