  2. Open-circuit voltage - Wikipedia

    en.wikipedia.org/wiki/Open-circuit_voltage

    Open-circuit voltage (abbreviated as OCV or V OC) is the difference of electrical potential between two terminals of an electronic device when disconnected from any circuit. [1] There is no external load connected. No external electric current flows between the terminals.

  3. Volatile organic compound - Wikipedia

    en.wikipedia.org/wiki/Volatile_organic_compound

    Volatile organic compounds (VOCs) are organic compounds that have a high vapor pressure at room temperature. [1] They are common and exist in a variety of settings and products, not limited to house mold, upholstered furniture, arts and crafts supplies, dry cleaned clothing, and cleaning supplies. [2]

  4. Photoionization detector - Wikipedia

    en.wikipedia.org/wiki/Photoionization_detector

    In a photoionization detector, high-energy photons, typically in the vacuum ultraviolet (VUV) range, break molecules into positively charged ions. [2] As compounds enter the detector they are bombarded by high-energy UV photons and are ionized when they absorb the UV light, resulting in ejection of electrons and the formation of positively charged ions.

    Schematic of a flame ionization detector for gas chromatography. A flame ionization detector (FID) is a scientific instrument that measures analytes in a gas stream. It is frequently used as a detector in gas chromatography.

  8. LCR meter - Wikipedia

    en.wikipedia.org/wiki/LCR_meter

    An LCR meter is a type of electronic test equipment used to measure the inductance (L), capacitance (C), and resistance (R) of an electronic component. [1] In the simpler versions of this instrument the impedance was measured internally and converted for display to the corresponding capacitance or inductance value.

  9. Transducer - Wikipedia

    en.wikipedia.org/wiki/Transducer

    A transducer is a device that converts energy from one form to another. Usually a transducer converts a signal in one form of energy to a signal in another. [1] Transducers are often employed at the boundaries of automation, measurement, and control systems, where electrical signals are converted to and from other physical quantities (energy, force, torque, light, motion, position, etc.).
