Question

what is transistor and name the types of transistor

Answer 1

Answer:

Transistor: A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor's terminals controls the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. Today, some transistors are packaged individually, but many more are found embedded in integrated circuits.

Types of transistors: Transistors are basically classified into two types; they are Bipolar Junction Transistors (BJT) and Field Effect Transistors (FET). The BJTs are again classified into NPN and PNP transistors. The FET transistors are classified into JFET and MOSFET.

Answer 2

$\huge \mathfrak{Answer:-}$

It is also the device which having generally three pins. There are called as emitter base and collector, it is the combination of the two p - n junction. Transistor is a Amplifier.

$\large\underline\mathrm\blue{Two \: types \: \: of \: transistors:-}$

$\large\underline\mathrm\red{1. \: p \: - \: n \: - \: p \: transistor}$

When the transistor is working then it's 1st p - n junction is always inforward baising.

$\large\underline\mathrm\red{2. \: n \: - \: p \: - \: n \: transistor}$

The n - p - n transistor amplifies the weak signal enter into the base and produces strong amplify signals at the collector end.
