You might think that a symptom on your tongueâsuch as an unusual color or textureâis no big deal, but what happens in your mouth can often be a helpful glimpse into your overall health. Sometimes symptoms that show up on your tongue can signal other health conditions, such as diabetes, vitamin deficiencies, and even scarlet fever.
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.

Transistor. A transistor is a basic electrical component that alters the flow of electrical current. Transistors are the building blocks of integrated circuits, such as computer processors, or CPUs.Modern CPUs contain millions of individual transistors that are microscopic in size.ransistor.
