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 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.


Why a transistor is called a transistor?

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)


What is unmodulated signal from a transistor is called?

When the out from a transistor is the exact replic of the input signal then it is called unmodulated signal i e. there will not be any change in frequency voltage power etc


What is transistor biasing and what is its need?

when transistor is subjected to an external power supply threw the biasing registors then it is called biasing. biasing is used to fix the Q-point of the transistor.


What are the leads of a transistor called?

For a bipolar junction transistor: * Emitter * Collector * Base For a field-effect transistor: * Drain * Source * Gate


Why RC couple is called transistor?

Its not!


Why is MOSFET called IGFET?

Insulated gate field effect transistor


How do you identify a pnp or npn transistor?

if the arrow of emitter terminal is outwards is called npn transistor otherwise if the arrow of the emitter terminal of a transistor is inwards is called pnp transistor A/ On a diagram a NPN the arrow will indicate the current flow as the emitter a line is the base. An pnp will follow the same principle With a meter you may certify this principle by noting leads polarity


What is the difference between a switching transistor and an ordinary transistor?

In the switching transistor the output current is controlled by the (current) and this is also called current controlled current device (CCCD). But in ordinary switch we controlled output current physically...


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.


What are the three terminals of a transistor called?

Emitter, Base, Collector.


Why bipolar junction transistor is called current controlling device?

When bipolar junction transistor(BJT) is operated under proper biasing large current flows through the BJT,thus it is called current operated device.


What do you called the center element between the emitter and collector in a transistor?

The base.


What is the transistor element?

Transistor is usually constructed using semiconductor elements. Semiconductor elements refers to partial conductors. They are neither full nor non conductors. that semiconductor elements may be called as transistor elements


Why operating point of transistor is called as q point?

Q-point means motionless point. At operating point the transistor emitter current and collector current doesn't change. That is why operating called as a quiesent point (q-point)


What is Si transistor?

A silicon transistor is a transistor made of silicon.


What is the Q point of a Transistor?

it is called as quiscient point. it is used to fix the transistor in the required region. it is plotted in the dc load line of transfer characteristics of a transistor. if the q point is in the middle of the load line the transistor amplifies the input signal since it is in active region and if the q point is in the bottom of the load line the transistor becomes off and it is said to be in cut-off region and if the q point is placed at the top of the load line the transistor is said to be in saturation region and more current flows through it.


Different between power transistor and transistor that used in small signal?

Power transistor can conduct large amount of currents through it, more than small signal transistor. power transistor has a vertical structure and small signal transistor has horizontal structure.In power transistor quasi saturation region is present which is absent in the small signal transistor. In power transistor there is a inculsion of drift layer which is not there in the small signal transistor. Power dissipation is less in power transistor and it is more in small signal transistor. b.v.polytechnic,vasai pushkar vaity.


Active region in transistor?

The active region of a transistor is when the transistor has sufficient base current to turn the transistor on and for a larger current to flow from emitter to collector. This is the region where the transistor is on and fully operating.


What is a load line of transistor?
