A glass or metal container that prevents air molecules from disrupting electron flow. Common Types

A (or thermionic valve) is an electronic component that controls electric current flow within a high-vacuum sealed container. Primarily used in early electronics, they amplify, switch, or regulate signals by controlling the movement of electrons emitted from a heated surface. Core Components vacuum tube

Placed between cathode and anode to control the volume of electrons. A glass or metal container that prevents air

Include additional grids to improve efficiency and reduce signal distortion. vacuum tube

Positively charged electrode that attracts the electrons.
