FAQ
Frequently Asked Questions
No, it is an obsolete technology largely replaced by solid-state (transistor-based) amplifiers and digital controllers from the 1960s onwards.
To use a small electrical input signal to precisely control a much larger output of electrical power, acting as a high-power amplifier in control systems.
In historical applications like WWII and post-war naval gun fire-control systems, industrial steel mill controls, and early analogue computer servomechanisms.
No, it is an extremely rare and specialised technical term. Most native English speakers, even engineers, may not know it unless they study historical technology.
