How Vacuum Tubes Really Work.
Vacuum tubes rely on hot cathodes emitting electrons and a plate attracting them to create current. A grid in between controls the current flow, enabling amplification. This article explores the nitty-gritty of how it works, including how cathode type, temperature, and electrode spacing affect the process. It explains the physics behind electron emission, space charge, and amplification factor, offering a deeper understanding than the basic principles.
