What is transistor short notes?
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.
What is the use of transistor in 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 is transistor and its working?
A transistor is a type of a semiconductor device that can be used to both conduct and insulate electric current or voltage. A transistor basically acts as a switch and an amplifier. In simple words, we can say that a transistor is a miniature device that is used to control or regulate the flow of electronic signals.
What is the full name of transistor?
The MOSFET (metal–oxide–semiconductor field-effect transistor), also known as the MOS transistor, was invented by Mohamed Atalla and Dawon Kahng at Bell Labs in 1959….History of the transistor.
| Year | Technology | Organization |
|---|---|---|
| 1947 | Point contact | Bell Labs |
| 1948 | Grown junction | Bell Labs |
| 1951 | Alloy junction | General Electric |
| 1953 | Surface barrier | Philco |
Why 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 transistor and types?
A transistor is a semiconductor device used to amplify or switch electronic signals. Transistors are broadly divided into three types: bipolar transistors (bipolar junction transistors: BJTs), field-effect transistors (FETs), and insulated-gate bipolar transistors (IGBTs).
How transistors make computers work?
A tiny electric current flowing through one part of a transistor can make a much bigger current flow through another part of it. In other words, the small current switches on the larger one. This is essentially how all computer chips work.
What is transistor with example?
1. 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.
Why do transistors work?
A transistor works when the electrons and the holes start moving across the two junctions between the n-type and p-type silicon. The small current that we turn on at the base makes a big current flow between the emitter and the collector.
What is a transistor?
What is a Transistor? A transistor is a type of a semiconductor device that can be used to both conduct and insulate electric current or voltage. A transistor basically acts as a switch and an amplifier.
What is the collector current of a transistor?
The transistor is in the active region and the collector current is depend on the emitter current. The transistor, which operates in this region is used for amplification. FF – In this condition, both the junction is in forward biased. The transistor is in saturation and the collector current becomes independent of the base current.
Why do transistors act like a closed switch?
The transistors act like a closed switch. RR – Both the current are in reverse biased. The emitter does not supply the majority charge carrier to the base and carriers current are not collected by the collector. Thus the transistors act like a closed switch.
How many types of transistors are there in circuits?
Based on how they are used in a circuit there are mainly two types of transistors. The three terminals of BJT are base, emitter and collector. A very small current flowing between base and emitter can control a larger flow of current between the collector and emitter terminal.
