Login mean. An example of type designation is K15I = 1, which denotes a constant-capacitance ceramic capacitor for pulsed operation. The specific capacity of such capacitors approaches that of electrolytic capacitors, but film capacitors have better electrical characteristics and permit operation with sign-variable voltage. Condenser as well means an optical system which focuses light beams from a light source into a narrower beam. The following year… Be sure to check the front section of the drawing set for the abbreviations used within. Furnace: There are gas (the most common), oil, and electric furnaces. The course is divided in 4 sections: Capacitors with a solid inorganic dielectric may have glass, vitreous enamel, glass ceramics, ceramics (for low and high frequencies), or mica. An electric component which consists of conducting plates insulated from each other by a layer of dielectric material; introduces, a device for accumulating electric charge, usually consisting of two conducting surfaces separated by a dielectric. 2. Condenser definition is - one that condenses: such as. The first and most common is the ladder diagram, so called because it looks like the symbols that are used to represent the components in the system have been placed on the rungs of a ladder. The disadvantage of mica capacitors is their low time and temperature stability of capacitance, particularly for capacitors with electrodes made of foil. An electrical device capable of storing electrical energy. Wired between the power and ground planes, they quickly charge up when the computer is turned on. • CONDENSER (noun) The noun CONDENSER has 4 senses:. Voilà, we have converted sound into an electrical signal. Electrolytic capacitors have high specific capacity, losses, and leakage current and a low capacitance stability. Variconds increase their capacitance upon an increase in the voltage across the capacitor plates. We Need an Electric Charge As was explained in our previous tutorial “What is a Condenser Microphone”, a condenser capsule constitutes a capacitor whose capacitance changes to the rhythm of the soundwaves that hit the diaphragm. The use of capacitors is expedient only at frequencies f < f0 (f0 is the natural resonance frequency of the capacitor), since for f > f0 the impedance is predominantly inductive. A device which consists essentially of two conductors (such as parallel metal plates) insulated from each other by a dielectric and which introduces capacitance into a circuit, stores electrical energy, blocks the flow of direct current, and permits the flow of alternating current to a degree dependent on the capacitor's capacitance and the current frequency. The points and condenser system works with an electrical charge that is sent to an ignition coil, which was connected to the distributor cap. The resistor sets the gain and output impedance. This information should not be considered complete, up to date, and is not intended to be used in place of a visit, consultation, or advice of a legal, medical, or any other professional. The Condenser is an apparatus or container for condensing vapor into liquid. In paper capacitors special capacitor-grade paper is the dielectric; paper capacitors have relatively high losses and a higher specific cost. The capacitance of a capacitor depends primarily upon its shape and size and upon the relative permittivity εr of the medium between the plates. Capacitors with a solid organic dielectric are manufactured by winding long, thin ribbons of dielectric and foil (capacitor plate); plates in the form of a layer of metal (zinc or aluminum) 0.03–0.05 micron thick deposited on the dielectric are sometimes used. The condenser coil can be made of copper tubing with aluminum fins or all-aluminum tubing so heat can be rapidly transferred. • Electret microphones use a polarised condenser instead of a crystal. Humidistat. Menu. | Meaning, pronunciation, translations and examples The most common dielectrics are silicon nitride and silicon dioxide. In varicaps the dependence of the width of the p-n junction on the applied voltage is used to change the capacitance: it decreases as the voltage increases, because of an increase in the width of the p-n junction. The condenser is a small electrical device connected across the contact-breaker points in the distributor. It is a non-polar capacitor having fixed capacitance value. Alternating Current (AC) Electrical … The points and condenser system is normally found on older model vehicles, such as classic cars. 1. an electrical device characterized by its capacity to store an electric charge 2. an apparatus that converts vapor into liquid 3. a hollow coil that condenses by abstracting heat 4. lens used to concentrate light on an object Familiarity information: CONDENSER used as a noun is uncommon. Dictionary entry overview: What does electrical condenser mean? HVAC term for a valve, either manual or automatic, that is used to remove unwanted air from the highest point of a piping system. In electrolytic (oxide) capacitors the dielectric is an oxide film deposited electrolytically on the surface of an aluminum, tantalum, niobium, or titanium plate that serves as one of the capacitor plates. Core elements, capacitator Two or more electrical conductors separated by a insulator. electrical appliance, electrical device [Hyper.] This type of capacitor is recommended for use in low-voltage, low-frequency circuits. The designation KN (nonlinear capacitor) has been established for capacitors with electrically adjustable capacitance; the third index denotes a primary capacitor parameter (amplification factor), and the fourth denotes the purpose of the capacitor. A capacitor (originally known as a condenser) is a passive two-terminal electrical component used to temporarily store electrical energy in an electric field. Variable capacitors with a solid dielectric (ceramics, mica, glass, or film) are used primarily for minor changes in capacitance (as semivariable or trimming capacitors). In general, a capacitor consists of two metal plates insulated from each other by a dielectric. Symbolized C. Also known as condenser; electric condenser. And not every unit is built the same way. The operating voltage for constant-capacitance vacuum capacitors is 5–45 kV. The parameters, design, and area of use of a capacitor are determined by the dielectric separating its plates; therefore, capacitors are classified primarily by the type of their dielectric. Inside those compact units are electrical connections, fans, compressors, condensers, switches, coolants—the list goes on and on. and low-frequency (high specific reactive power). Therefore, electrolytic capacitors are usually used only in DC circuits or in circuits with currents pulsating at a low frequency (up to 20 kHz) as blocking capacitors, in decoupling circuits, and in electrical filters. It is comprised primarily of the heating and (often) cooling sources, as well as the ductwork that circulates the warm or cold air and a control unit. 2. Capacitors have inductance L. As a result, the impedance of a capacitor is often not predominantly capacitive in any frequency range. AC and heating units are kind of like cars—they share most of the same components, but they … • ELECTRICAL CONDENSER (noun) The noun ELECTRICAL CONDENSER has 1 sense:. Also — The calculations for the MCA and MOP are based on requirements of NFPA 70, the National Electrical Code (NEC) and CSA C22.1, the Canadian Electrical Code (CEC). Information and translations of electrical condenser in the most comprehensive dictionary definitions resource on the web. The two-terminal electret capsule contains a FET which must be externally powered by supply voltage V +. Film capacitors have high insulation resistance, high TCC, low losses, and relatively low specific cost. In mica capacitors, mica split into plates as thin as 0.01 mm serves as the dielectric. (Image courtesy of NVIDIA Corporation. The most appropriate frequency range for operation of vacuum capacitors is 1–10 MHz. In capacitors with mechanical adjustment, a change in capacitance is most frequently achieved by changing the area of the capacitor plates or (less frequently) by changing the gap between the plates. When more transistors switch simultaneously because the application demands extra processing, they are made to release their charge. 4. capacitor. https://encyclopedia2.thefreedictionary.com/electrical+condenser. The system established in the USSR for abbreviating model designations of capacitors with constant capacitance consists of four indexes. Capacitor-grade glass, low-frequency or high-frequency vitreous enamel, or glass ceramics may be the dielectric. Constant-capacitance air capacitors are used in measurement technology primarily as capacitance standards. Glass, vitreous-enamel, and glass-ceramic capacitors are multilayer packets consisting of alternating layers of dielectric and plate material (silver or other metal). The first index (a letter) is K (for capacitor; from Russian kondensator), the second (a numeral) describes the capacitor group in terms of its dielectric, the third (a letter) denotes the purpose of the capacitor (P—for operation in both AC and DC circuits, Ch—for operation in AC circuits, U—for operation in DC, AC, and pulsed circuits, and I—for pulsed operation; capacitors without this index letter are intended for operation in DC circuits and for pulsed operation), and the fourth is a design serial number. See Integrated circuits. They are formed, together with their connecting conductors and associated thick-film resistors, upon a ceramic substrate. The capacitance of a capacitor depends primarily upon its shape and size and upon the relative permittivity ε r of the medium between the plates. Heating Sources. Airflow Volume. Dictionary, Encyclopedia and Thesaurus - The Free Dictionary, the webmaster's page for free fun content, Electrical Engineering and Electronics Monopolies, Electrical Equipment of Transportation Vehicles, Electrical Circuit Characterization and Diagnostic, Electrical conduction system of the heart, †TCC not indicated for types of capacitors in which the changes in capacitance with temperature are relatively large and nonlinear, Looking like "silver cans," and acting like miniature storage batteries, capacitors are found on countless circuit boards such as this high-end display adapter. Effective use of paper capacitors is possible at frequencies up to 1 MHz. Paper capacitors are widely used in low-frequency, high-voltage circuits with high current intensity—for example, to increase the power factor (cos ϕ). Cr. Dictionary ! In vacuum capacitors the breakdown voltage does not depend on atmospheric pressure; therefore, they are widely used in aircraft equipment. In October 1745, Ewald Georg von Kleist of Pomerania, Germany, found that charge could be stored by connecting a high-voltage electrostatic generator by a wire to a volume of water in a hand-held glass jar. circuit, electrical circuit, electric circuit - distributer, distributor, electrical distributor [Desc] electrical condenser (n.) ↕ The electrodes of mica capacitors are made of foil or are deposited on the mica by evaporation of the metal in a vacuum or by firing. ... or dry air, used for storing an electric charge; condenser.

Humidity. A liquid, semiliquid, or paste electrolyte or semiconductor serves as the second plate. Vacuum capacitors have lower losses and a low TCC and are more vibration-resistant than gas-filled capacitors. These are usually single-layer capacitors. Measured in cubic feet per minute (cfm), this is the amount of air circulated in a space. The Drier is a kind of substance or device to accelerate the drying or extract moisture. Learn more. It … However, such capacitors have a high TCC and high dielectric losses; therefore they are not promising. The purpose of a high vacuum, or a gas under pressure, is to increase the voltage breakdown value for a given plate spacing.
