What are the three element of transistor?

For a BJT transistor the three basic elements are collector, base and emitter. For a FET transistor are drain, gate and source which are analogous for the BJT parts mentioned before.

How many region a transistor have?

A transistor typically has three regions: the emitter, the base, and the collector. In a bipolar junction transistor (BJT), these regions are crucial for its operation, with the emitter injecting charge carriers, the base controlling their flow, and the collector collecting them. In a field-effect transistor (FET), the three regions consist of the source, gate, and drain. Each region plays a vital role in the transistor's functionality and performance.


What is the difference between the UJT and BJT transistors?

UJT (UniJunction Transistor): It is a transistor with only one junction and three terminals: an emitter (E) and two bases (B1 and B2). BJT (Bipolar Junction Transistor): This type of transistor consists of two junctions and three terminals, namely Emitter "E", Base "B" and Collector"C". There are two types of BJT, i) PNP and ii) NPN.

What are the uses of BJT?

Bipolar junction transistors has two junctions base emitter junction, base collector junction. Accordingly there are four different regions of operation in which either of the two junctions are forward biased reverse biased or both. But the BJT can be effectively operated in there different modes according to the external bias voltage applied at each junction. i.e. Transistor in active region, saturation and cutoff. The other region of operation of BJT is called as inverse active region.


What are the three transitional layers in the atmosphere?

The three transitional layers in the atmosphere are the tropopause, which separates the troposphere and the stratosphere; the stratopause, which separates the stratosphere and the mesosphere; and the mesopause, which separates the mesosphere and the thermosphere.
