Grid bias — is a DC voltage applied to electron tubes (or valves in British English) with three electrodes or more, such as triodes. The control grid (usually the first grid) of these devices is used to control the electron flow from the heated cathode to… … Wikipedia
Current source — Figure 1: An ideal current source, I, driving a resistor, R, and creating a voltage V A current source is an electrical or electronic device that delivers or absorbs electric current. A current source is the dual of a voltage source. The term… … Wikipedia
Grid leak — is the small current through the grid of a thermionic valve into the circuit which feeds the grid. It is an inherent operating characteristic of triodes and other vacuum tubes.This current is caused by the small negative EMF which is present in… … Wikipedia
grid bias — n. a steady, direct current voltage applied to the control grid of an electron tube to make it negative with respect to the cathode … English World dictionary
Grid plan — A simple grid plan road map (Windermere, Florida). Surveyor s plan of Salt Lake City, ci … Wikipedia
Suppressor grid — A suppressor grid is a grid used in a thermionic valve (also called vacuum tube) to suppress secondary emission. A suppressor grid is also called the antidynatron grid, as it helps to reduce the dynatron effect. Placement In its simplest form, a… … Wikipedia
High-voltage direct current — HVDC or high voltage, direct current electric power transmission systems contrast with the more common alternating current systems as a means for the bulk transmission of electrical power. The modern form of HVDC transmission uses technology… … Wikipedia
Screen grid — The screen grid is a grid introduced into a vacuum tube (thermionic valve) to greatly reduce the capacitance between two other parts of the electrode structure.In its simplest form, a screen grid is placed between the control grid and anode or… … Wikipedia
