According to the Social Security Administration's annual rankings of baby names, Addison has yet to crack the top 10 among girls.
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.

Types of transistor. There are two types of standard (bipolar junction) transistors, NPN and PNP, with different circuit symbols. The letters refer to the layers of semiconductor material used to make the transistor. Most transistors used today are NPN because this is the easiest type to make from silicon.here are two types of standard (bipolar junction) transistors, NPN and PNP, with different circuit symbols.
