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 of terminals. Because the controlled (output) power can be much more than the controlling (input) power, the transistor provides amplification of a signal. Today, some transistors are packaged individually, but many more are found embedded in integrated circuits.
Why it is called transistor?
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 of terminals.
The transistor was invented in 1947 by John Bardeen, Walter Brattain, and William Shockley at Bell Labs. The word transistor is a combination of the two words "transfer" and "resistor". This name was chosen because the device's function is to transfer resistance from one circuit to another.
What is difference between diode and transistor? Diodes and transistors are both electronic devices that can be used for a variety of purposes. Diodes are typically used to rectify AC to DC, while transistors are used to amplify or switch electronic signals. The main difference between diodes and transistors is that diodes only allow current to flow in one direction, while transistors can be used to control the flow of current in either direction. Where is transistor used? A transistor is a semiconductor device that can be used to amplify or switch electronic signals. Transistors are made of materials like germanium and silicon. They are found in almost all electronic devices, including radios, computers, and cell phones.
Why is transistor used?
A transistor is a semiconductor device that can be used to amplify or switch electronic signals. A transistor consists of three terminals: a source, a gate, and a drain. When a voltage is applied to the gate, it controls the current flowing between the source and the drain.
Transistors are used in a wide variety of electronic devices, including amplifiers, computers, and radios. They are also used in digital circuits, as they can be used to switch signals on and off.
