Frequency — For other uses, see Frequency (disambiguation). Three cyclically flashing lights, from lowest frequency (top) to highest frequency (bottom). f is the frequency in hertz (Hz), meaning the number of cycles per second. T is the period in seconds (s) … Wikipedia
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
Grid energy storage — is used to manage the flow of electrical energy. For large scale load levelling on an interconnected electrical system, electric energy producers send low value off peak excess electricity over the electricity transmission grid to temporary… … 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 plan — A simple grid plan road map (Windermere, Florida). Surveyor s plan of Salt Lake City, ci … Wikipedia
Grid friendly — Electrical devices are considered grid friendly if they operate in a manner that supports electrical power grid reliability. Basic grid friendly devices may incorporate features that work to offset short term undesirable changes in line frequency … Wikipedia
Grid tie inverter — A grid tie inverter, or a (GTI) is an electrical device that allows solar power users to complement their grid power with solar power. It works by regulating the amount of voltage and current that is received from the direct current solar panels… … Wikipedia
Grid cells — A grid cell is a type of neuron found in the entorhinal cortex (EC) that fires strongly when an animal is in specific locations in an environment. Grid cells were discovered in 2005 and it is hypothesized that a network of these cells constitute… … Wikipedia
Grid dip oscillator — Dipmeter could also refer to an influential early commercial expert system called Dipmeter Advisor; or may refer to an instrument that measures the dip angle of the planet s magnetic field, the field line angle in a vertical plane. A dipmeter and … Wikipedia
Grid-leak detector — A grid leak detector is a combination diode rectifier and audio amplifier used as a detector in vacuum tube A.M. radio receivers. In the circuit, the grid of the detector usually a low mu or medium mu triode is connected to the secondary of the… … Wikipedia
