PENTAGRID Meaning and
Definition
-
Pentagrid is a term that refers to a specific framework or arrangement found in electronic or electrical systems, particularly in vacuum tube technology. It consists of a five-element electrode system that is used in the construction of pentode vacuum tubes.
The term "pentagrid" originates from the combination of "penta," which means five, and "grid," which refers to an electrode that controls the flow of electrons in vacuum tubes. Therefore, a pentagrid consists of five grids or electrode elements.
In a pentagrid tube, the five elements typically include a cathode (also known as the filament), a control grid, a screen grid, a suppressor grid, and a plate. The cathode serves as the source of electrons, while the control grid determines the flow of electrons through the tube, thereby controlling its amplification or modulation abilities. The screen grid acts as an intermediate electrode, while the suppressor grid helps in improving the overall performance by reducing secondary emissions from the plate. Lastly, the plate collects the electrons emitted from the cathode, creating the desired output.
Pentagrids are commonly used in various electronic applications like receivers, amplifiers, and communication devices due to their efficient performance. The unique design of pentagrid tubes allows for more precise control over the electronic signal, leading to enhanced amplification and signal processing capabilities.
Overall, the term "pentagrid" refers to a specialized arrangement of five electrode elements in vacuum tubes, enabling efficient and accurate control of electron flow, making it an important component in electronic systems.

Etymology of PENTAGRID
The word "pentagrid" is derived from the combination of two parts: "pent" and "grid".
1. "Pent" is derived from the Greek word "pente", meaning "five". This prefix is commonly used to denote the number five in various contexts.
2. "Grid" refers to a network of intersecting parallel lines or wires. In this context, it specifically refers to the arrangement of electrodes or pins in a vacuum tube or valve.
Therefore, the term "pentagrid" is used to describe a specific type of vacuum tube or valve that incorporates a grid arrangement with five intersecting parallel lines or wires.
