vaakumtorud
Vaakumtorud, also known as vacuum tubes, are electronic devices that control electric current between two electrodes separated by a vacuum. They were widely used in electronic devices before the advent of solid-state electronics. The basic structure of a vacuum tube consists of a cathode, which emits electrons, and an anode, which collects them. The space between the electrodes is maintained under a vacuum to prevent the electrons from colliding with gas molecules.
Vacuum tubes operate based on the principle of thermionic emission, where electrons are emitted from the cathode
Vacuum tubes were crucial in the development of early electronic devices such as radios, televisions, and computers.
The invention of the transistor in the mid-20th century marked the beginning of the end for vacuum
Despite their decline, vacuum tubes continue to be used in certain specialized applications, such as high-power
