Transistor is called Bi-Polar device because the current can be flow due to electron and holes, hence it is called bipolar.

Why high noise in bipolar junction transistor?

In the case of Bipolar Junction Transistor current conduction is due to both holes and electrons. That's why noise is high in Bipolar Junction Transistor


What is FET?

FET is abbreviation of Field Effect Transistor. This is a transistor in which current is controlled by voltage only and no current is drawn. It is a high input impedence device and is used in computers, telecommunication and control circuits. This transistor is better in certain parameters as compared to BJT, that is Bipolar Junction Transistor.

Why ordinary transistor is known as bipolar junction transistor?

Transistor is known as bipolar junction becoz it has 2 pole. Input is given to the 2 junction and output is taken from to junction


Why bjt is bipolar?

BJT stands for bipolar junction transistor because it is composed of two types of semiconductors (P and N-type) rather than just one type like a unipolar transistor. This allows for both electron and hole current flow in the device, giving it its bipolar characteristic.


Is junction transistor and bipolar junction transistor are same?

Yes, the are different names for the same thing.


What is the difference between a bipolar transistor and a field effect transistor?

A bipolar transistor uses both majority and minority charge carriers for conduction, while a field effect transistor primarily relies on majority charge carriers. Field effect transistors have a higher input impedance compared to bipolar transistors. Additionally, bipolar transistors are current-operated devices, while field effect transistors are voltage-operated devices.
