What is the function of transistor PDF?
Transistors amplify current, for example they can be used to amplify the small output current from a logic IC so that it can operate a lamp, relay or other high current device. In many circuits a resistor is used to convert the changing current to a changing voltage, so the transistor is being used to amplify voltage.
What are the types of transistor?
Transistors are broadly divided into three types: bipolar transistors (bipolar junction transistors: BJTs), field-effect transistors (FETs), and insulated-gate bipolar transistors (IGBTs).
What is a transistor explain?
A transistor is a semiconductor device used to amplify or switch electrical signals and power. The transistor is one of the basic building blocks of modern electronics. It is composed of semiconductor material, usually with at least three terminals for connection to an electronic circuit.
What is the principle of transistor?
The basic idea behind a transistor is that it lets you control the flow of current through one channel by varying the intensity of a much smaller current that’s flowing through a second channel. A transistor is a semiconductor device with three terminals, capable of amplification and rectification.
What is the symbol of transistor?
Table of transistor symbols
| Name | Description |
|---|---|
| PNP Bipolar Transistor | Allows current flow when low potential at base (middle) |
| Darlington Transistor | Made from 2 bipolar transistors. Has total gain of the product of each gain. |
| JFET-N Transistor | N-channel field effect transistor |
| JFET-P Transistor | P-channel field effect transistor |
What are the 3 terminals of a transistor called?
The BJT (bipolar junction transistor) is a current-controlled electronic device main employed for amplification and switching purpose. It comes with three terminals called emitter, base, and collector. The small current at the base side is used to control the large current at the remaining terminals.
What is the main use of a transistor?
transistor, semiconductor device for amplifying, controlling, and generating electrical signals. Transistors are the active components of integrated circuits, or “microchips,” which often contain billions of these minuscule devices etched into their shiny surfaces.
Does transistor work on AC or DC?
As we said before, transistors are DC components. This means that the output will also be a DC voltage. But if we amplify an AC voltage, then we probably want to get an AC voltage at the output as well.
Why are transistors so important?
Transistors make excellent electronic switches. They can turn currents on and off billions of times per second. Digital computers use transistors as a basic mechanism for storing and moving data.
Who invented transistor?

Transistor/Inventors
The three physicists who invented the transistor; William Shockley, John Bardeen, and Walter Brattain were awarded with the Nobel Prize.
What is an example of a transistor?
The definition of a transistor is an electronic device that works by controlling the flow of the electrical current. An example of a transistor is something combined in large numbers with microcircuits into a single circuit board and used in a computer. YourDictionary definition and usage example. “Transistor.”.

What are the components of a transistor?
They are composed of a semiconductor material with at least three terminals for connection to an external circuit. Transistors are the key active components in practically all modern electronics. Transistors are categorized by: (1)Semiconductor material: graphene, germanium, silicon, gallium arsenide, silicon carbide,…
What is Transistor Theory?
The Theory: A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. It is composed of semiconductor material with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor’s terminals changes the current through another pair…
