A transistor is a three-terminal electronic component composed of semiconducting material such as silicon or germanium. the purpose of a transistor is to use a small signal to vary the conductivity of a piece of semiconductor. The tiny signal can switch a large current on and off. Or, the signal can be used to control a larger signal, so the transistor becomes an amplifier. In Bipolar Junction transistors the large current must pass across an extremely thin insulating layer, and the width of this insulating layer controls the current.
In Field Effect Transistors the large current must pass through a narrow conductive channel with insulating layers on either side. The width of this conductive channel controls the current.

What is composite transistor?
A Darlington transistor is a composite transistor. The definition is a combination of two or more transistors that have the purpose of increasing the current gain.
What is the definition of AND gates?
AND gates are parts of electronic transistor circuitry.
In what ways can a transistor amplifier modulator be modulated?
If I remember correctly, the definition of "modulation" is a "change in amplitude or frequency".
What is the purpose of transister?
The correct spelling is transistor. The definition of transistor is a portable radio that uses circuits that contain transistors instead of vacuum tubes. It is a semiconductor device that has three connections.
What is Si transistor?
A silicon transistor is a transistor made of silicon.
Is active is a cutoff region of 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 the purpose of the Unijunction Transistor?
A Unijunction Transistor is a transistor that acts solely as a switch.

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.
