Concept of Vacuum tube and its functions

As per the concepts of electronics, vacuum tube is a device which controls electric current between electrodes in an evacuated container. Basically, vacuum tube mostly rely on thermionic emission of electrons from a hot filament or a cathode heated by the filament. It consists of two or more electrodes in a vacuum inside with a airtight enclosure.

Vacuum tube was invented by the great scientist John Fleming in 1904. It was widely applicable in various electronic devices like radio, television, radar, sound reinforcement, sound recording and reproduction, large telephone networks, analog and digital computers, and industrial process control.

Vacuum bottle is a bottle or flask having a vacuum liner that prevents the escape of heat from hot contents, usually liquids, or the entrance of heat into cold contents. Scientifically it can be defined as a container with a double wall and a partial vacuum in the space between the two walls. Vacuum bottles are used to minimize the transfer of heat between the inside and the outside. This is how it keeps the contents at a desired temperature.

Like wise a vacuum chamber is a rigid enclosure from which air and other gases are removed by a vacuum pump which results in a low pressure environment within the chamber, commonly referred to as a vacuum. These chambers often have multiple ports, covered with vacuum flanges, in order to allow instruments or windows to be installed in the walls of the chamber. As per the concept, arc-extinguish chamber contains of metal part and plastic chamber and serves for extinguishing of electrical arc
