Positively charged electrode that attracts the electrons.
Introduced the grid for amplification.
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. Positively charged electrode that attracts the electrons
A glass or metal container that prevents air molecules from disrupting electron flow. Common Types vacuum tube
Examples include "magic eye" tubes for signal display, thyratrons, and magnetrons. Key Technical Details
Include additional grids to improve efficiency and reduce signal distortion.
