Review of Short Phrases and Links

    This Review contains major "Capacitance"- related terms, short phrases and links grouped together in the form of Encyclopedia article.

Definitions

  1. Capacitance is a measure of the amount of electric charge stored (or separated) for a given electric potential. (Web site)
  2. CAPACITANCE is similar to inductance because it also causes a storage of energy.
  3. Capacitance is a measure of the amount of feelings stored (or seperated) for a given level of insulation.
  4. Capacitance - The ability of a dielectric material between conductors to store energy when a difference of potential exists between the conductors.
  5. Consistent use of the word "capacitance" for C avoids this conceptual error.

Capacitance

  1. The capacitance of a single object, say an isolated sphere, is determined by considering the other plate to be an infinite sphere surrounding it. (Web site)
  2. A common misunderstanding about electrical capacitance is to assume that capacitance represents the maximum amount of charge a capacitor can store.
  3. However, ceramic capacitors tend to vary their capacitance with temperature.
  4. The capacitance of the earth, if considered as an isolated conducting sphere, is about 680 --F.
  5. Semtech RailClamps are low capacitance TVS arrays designed to protect high speed data interfaces.

Circuit

  1. Combining impedances in parallel is much more difficult than combining simple properties like resistance or capacitance, due to a multiplication term. (Web site)
  2. Others may make use of the movement to change the air gap between two capacitance plates, causing a change in the current in the circuit.
  3. Tantalum capacitors have high capacitance and low ESR, but low operating voltages.
  4. This time, in seconds, is found by multiplying the resistance in ohms and the capacitance in farads.
  5. Reactance arises from the presence of inductance and capacitance within a circuit, and is denoted by the symbol , the SI unit is the ohm.

Impedance

  1. Additionally, the impedance for a capacitance is negative imaginary while the impedance for an inductor is positive imaginary. (Web site)
  2. For digital audio, or for video, impedance is relevant and capacitance is practically irrelevant. (Web site)

Charge

  1. Consider a capacitance C, holding a charge +q on one plate and -q on the other. (Web site)
  2. If a capacitor with charge on its plates has a capacitance of, say, 2 microfarad, then its capacitance is also 2 microfarad when the plates have no charge. (Web site)

Farad

  1. Capacitance densities in excess of 30 Farads per gram of carbon is easily realized.
  2. The capacitance of the majority of capacitors used in electronic circuits is several orders of magnitude smaller than the farad. (Web site)
  3. The farad (symbol F) is the SI unit of capacitance (named after Michael Faraday). (Web site)

Conductors

  1. The SI unit of capacitance is the farad; 1 farad = 1 coulomb per volt. (Web site)
  2. Capacitance exists between any two conductors insulated from one another.
  3. Typical microphone cable has around typically around 50-70 pF capacitance between the conductors and around 90-130 pF capacitance from conductor to shield. (Web site)
  4. Farad Unit of electrical capacitance, equivalent to 1 coulomb of stored charge per volt of applied potential difference.
  5. When running coaxial cable in a video system, attenuation is a function of its length due to distributed capacitance.

Dielectric

  1. The capacitance can be calculated if the geometry of the conductors and the dielectric properties of the insulator between the conductors are known. (Web site)
  2. Therefore the capacitance of a capacitor can be increased by increasing the permittivity of the dielectric material inside it.
  3. The cable capacitance is simply a function of the diameter ratios of the inner and shield, and the permittivity of the dielectric. (Web site)

Reactance

  1. Capacitive reactance is inversely proportional to the signal frequency and the capacitance .
  2. Reactance in an a-c circuit containing capacitance which causes a lagging voltage.
  3. Capacitive Reactance The opposition to alternating current due to the capacitance of a cable or circuit.

Capacitor

  1. The capacitance of a capacitor is measured by this procedure: Put equal and opposite charges on its plates and then measure the potential between the plates. (Web site)
  2. The size of the capacitor's capacitance is the same whatever the charge and potential (assuming the dielectric constant doesn't change). (Web site)

Crystal

  1. Holder capacitance The sum of the stray capacity contributed by the crystal connected between the two leads of the resonator.
  2. C1 The abbreviation for motional capacitance.
  3. The CO, or shunt capacitance, represents the capacitance of the crystal electrodes plus the capacitance of the holder and leads.

Load

  1. Serena Industries - Manufacturer of capacitive load cells, capacitance to voltage converters, and related electronics.
  2. This frequency is dependent upon the crystal design and the amount of load capacitance, if any, the oscillator circuit presents to the crystal.

Quartz

  1. The motional capacitance (C1) represents the elasticity of the quartz, and the resistance (R1), represents bulk losses occurring within the quartz.
  2. Motional capacitance may be abbreviated as "Cm" or "C1." The actual value of C1 has physical limitations when it is realized in a quartz crystal design.

Shunt

  1. C0 Abbreviation for shunt capacitance.
  2. Measured in picoFarads (pF), shunt capacitance is present whether the device is oscillating or not (unrelated to the piezoelectric effect of the quartz).
