What is Vacuum Tube ?

with all the air removed since air can act as a conductor when energized

the development of analog and digital computers.

because of the shape of the vacuum, it became commonly known as the vacuum tube.

It was essentially the predecessor of the modern transistor

which brought about a revolution in technology and paved the way for the development of the personal computer.

Because the vacuum tube needed a heating filament to produce electrons, it usually

The vacuum tube was composed of a cathode that produces electrons and an anode that collects the electrons

leading to the quick degradation of the components,

it burned out rather quickly

at least the very basic ones called a diode

other types of vacuum tubes existed that were classified according to the number of electrodes present.

It also required three different power sources of varying capacities

vacuum tube technology progressed

point where the tubes were as small as large Christmas lights.

Vacuum tubes, however, are not completely

big radio stations and high-power

those utilizing power levels above 10,000 W and frequencies above 50 MHz

The reason is cost-efficiency since transistors are really just good for low frequencies

with all the air removed since air can act as a conductor when energized enough

because of the shape of the vacuum, it became commonly known as the vacuum tube.

high frequencies, a hundred transistors in parallel and wired together

the vacuum tube needed a heating filament to produce electrons

which creates massive heat, so heat sinks are required.

it usually required massive amounts of power and thus produced a lot of heat

An equivalent transmitter will only use a single tube
