In the world of electronics, vacuum tubes have been an integral part of many inventions. They are also commonly known as valves due to their role in regulating and controlling electricity.

Valves act like valves on a pipe, allowing electrons to flow through them at different rates while maintaining control over the current. Just like a valve can be used to regulate water pressure or temperature, electronic valves can be used to modify signals within circuits and components.
