What is transistor in simple words?
A transistor is a device that regulates current or voltage flow and acts as a switch or gate for electronic signals. Transistors consist of three layers of a semiconductor material, each capable of carrying a current. A transistor regulates current or voltage flow and acts as a switch or gate for electronic signals.
What is meant by transistor definition?
1 : a solid-state electronic device that is used to control the flow of electricity in electronic equipment and usually consists of a small block of a semiconductor (such as germanium) with at least three electrodes. 2 : a transistorized radio.
What is a transistor and its uses?
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.
What is transistor and example?
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. noun. 8.
Why it is called transistor?
The word transistor is a combination of transfer and resistance. This is because it transfers the resistance from one end of the device to the other end or we can say, transfer of resistance. Hence, the name transistor. Transistors have very high input resistance and very low output resistance.
What is the purpose of transistor?
Transistors are a three terminal semiconductor device used to regulate current, or to amplify an input signal into a greater output signal. Transistors are also used to switch electronic signals. The circulation of electrical current through all types of transistors is adjusted by electron addition.
What is transistor with diagram?
Diagram ‘A’ shows an NPN transistor which is often used as a type of switch. A small current or voltage at the base allows a larger voltage to flow through the other two leads (from the collector to the emitter). The circuit shown in diagram B is based on an NPN transistor.
How transistors work in computers?
A transistor works when the electrons and the holes start moving across the two junctions between the n-type and p-type silicon. By turning a small input current into a large output current, the transistor acts like an amplifier. But it also acts like a switch at the same time.
What is a transistor symbol?
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 |
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.
What does a transistor do in a computer?
In the digital world, a transistor is a binary switch and the fundamental building block of computer circuitry. Like a light switch on the wall, the transistor either prevents or allows current to flow through. A single modern CPU can have hundreds of millions or even billions of transistors.
What’s a transistor do?
A transistor is a miniature electronic component that can do two different jobs. It can work either as an amplifier or a switch: When it works as an amplifier, it takes in a tiny electric current at one end (an input current) and produces a much bigger electric current (an output current) at the other.
What does a transistor look like?
A typical transistor looks like a sandwich with one type of semiconductor as the slices of bread and the second type of semiconductor as the filling. For example, a thin slice of a p-type semiconductor might be placed between two thicker slices of an n-type semiconductor.
How do you use a transistor as a switch?
Some of the basic Applications of Transistor as a Switch. In a transistor, unless a current flows in the base circuit, there is no current can flow in the collector circuit. This property will allow a transistor to be used as a switch. The transistor can be switched ON or OFF by changing the base.
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,…
How does a transistor operate?
The transistor works because of something called a semiconducting material. A current flowing from the base to the emitter “opens” the flow of current from the collector to the emitter.
