Because in this device the resistance between two terminal respectively collector and emitter is changed by changing the base voltage that is it transfers the resistance between emitter and collector therefore it is called as TRANSISTOR. (TRANSFER OF RESISTOR)

transistor employin flow of both electron and holes for conduction is bipolar junction transistor.they are bipolar in nature.a bjt has two pn junctions, one between emitter and base and the other between base and collector.

a transistor employin both hole and electrons(major and minor charge carrier) for conduction is bipolar junction transistor.

No.


There is confusion above between electrons/holes and majority/minority carriers.


In P-type, majority carriers are holes, minorities are electrons.


In N-type, majority carriers are electrons, minorities are holes.


Generally, majority carriers are preferred, minority carriers are designed to be of as low density as possible.


The simplest distinction is that there are two different types of semiconductor, P-type and N-type, which may be PNP or NPN, and that the device uses a "sandwich" junction construction.

the transistor is called as transistor because there is transfer of resistance from input to output .transfer resistance so it is transistor.

Why transistor is called so?

transistor. This word is a blended form of transfer of resistor. The legs of transistor (collector, emitter,base) transfer the resistance. So it is called as transistor


Why RC couple is called transistor?

Its not!


Why transistor is called as bi-polar device?

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


Why transistor is called transfer of resistor?

Transistor=Transfer+Resistor. When Transistor operates in active region its input resistance is high and output resistance is low. So,We can consider transistor as a device which transfers its resistance from high to low. And by this property transistor amplifies input signal.

MOSFET is Metal Oxide Semiconductor Field Effect Transistor. IGFET Insulated Gate Field Effect Transistor. But these expressions are practically synonyms.


Why UJT is called as transistor?

Even though it has only two types of charge carriers we will not call it as a diode but a transistor since it is a three terminal device.
