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.

There are a lot of switches in the average computer chip that is in almost every device humans make these days. According to the Mooreâs Law article on wikipedia in 2008 the highest count of transistors on a chip was around 2 billion, but that was at extreme top end chip. The chips we are more familiar such as the low powered atom has 47 million, and the core intel i7 (quad) has 731 million according to wikipedia.
