what are its various types?
MOSFET (metal–oxide–semiconductor field-effect transistor)
Transistor
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.
what is distributed-element circuit? They are electrical circuits composed of lengths of transmission lines or other distributed components. what are some active components in it? diodes, transistors mention a few of the circuit's disadvantages? It takes up more space than lumped-element circuits and is problematic in hand-held mobile devices which has limited space. what is the second active component? It is a semiconductor device used to amplify or switch electronic signals and electrical power. how is it in comparison to the vacuum tubes? UNANSWERABLE

Transistor [SEP] Introduction
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. Transistors revolutionized the field of electronics, and paved the way for smaller and cheaper radios, calculators, and computers, among other things.
