This video about What is transistor (mosfet) and how it work in bangla/bengali with animation.

what is transistor, how it works and how transistor work as switch
and how it also work as amplifier you get all of this answers in this video in Bangla.

The transistor is just a switch that controls the flow of electricity.1 when there is electricity And 0 when there is no current. At present all kinds of information are stored in this process Being processed as well. All this has been made possible by semiconductor. which object does not transmit electricity very well also not behave like electricity conductors they are called semiconductors Such as pure silicone. When phosphorus is added to silicon it is called N type semiconductor or n type doping again When Boron is added to silicon it is called N type semiconductor or n type doping.
A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. It is composed of semiconductor material
usually with at least three terminals for connection to an external circuit.
A voltage or current applied to one pair of the transistor's terminals controls
the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. Today, some transistors are packaged individually, but many more are found embedded in integrated circuits.
Austro-Hungarian physicist Julius Edgar Lilienfeld proposed the concept of a field-effect transistor in 1926, but it was not possible to actually construct
a working device at that time. The first working device to be built was a point-contact transistor invented in 1947 by American physicists John Bardeen and Walter Brattain while working under William Shockley at Bell Labs. The three shared the 1956 Nobel Prize in Physics for their achievement. The most widely used transistor is the MOSFET (metal–oxide–semiconductor field-effect transistor), also known as the MOS transistor, which was invented by Mohamed Atalla with Dawon Kahng at Bell Labs in 1959.The MOSFET was the first truly compact transistor that could be miniaturised and mass-produced for a wide range of uses.
Most transistors are made from very pure silicon, and some from germanium, but certain other semiconductor materials are sometimes used. A transistor may have only one kind of charge carrier, in a field-effect transistor, or may have two kinds of charge carriers in bipolar junction transistor devices. Compared with the vacuum tube, transistors are generally smaller and require less power to operate. Certain vacuum tubes have advantages over transistors at very high operating frequencies or high operating voltages. Many types of transistors are made to standardized specifications by multiple manufacturers.
