What is a transistor?

The transistor is a semiconductor, differentiated from the vacuum tube primarily by using a solid, still part to hand over the hub. They are key components of virtually every piece of modern electronics and many are considered to be the most important invention of a modern age (as well as reporting information age). In 1947, researchers in Bell Laboratories introduced the first functional model after a series of false starts and technological blocks of injury. Texas instruments and in the early 1960s this radio became a support for the worldwide Market electronics. Also in the sixties, transistors were integrated into silicon chips and laid the foundations for technology that would eventually allow personal computers to become a reality. In 1956 Bill Shockley, Walter Brattain and John Bardee won the Nobel Prize for Physics for their development of the transistor.

primary type that is currently used is known as bipolar connecting transmissionItorus, which consists of three layers of semiconductor material, two of which have other electrons and one that has gaps. Two with extra electrons (type N) sandwiches with spaces (type P). This configuration allows the transistor to be a switch, closes quickly and opened as an electronic gate, allowing the voltage to pass at the specified speed. If this is not protected from light, light can be used to open or close the gate, in which case it is referred to as a phototransistor and acts as a high-sensitive photo.

The secondary type is known as a field effect transistor and consists of either a half -odent material of the N or a semiconductor type P type, while the current is controlled by the amount of voltage applied to it.
