  2. Wire gauge - Wikipedia

    en.wikipedia.org/wiki/Wire_gauge

    In commerce, the sizes of wire are estimated by devices, also called gauges, which consist of plates of circular or oblong form having notches of different widths around their edges to receive wire and sheet metals of different thicknesses. Each notch is stamped with a number, and the wire or sheet, which just fits a given notch, is stated to ...

  3. American wire gauge - Wikipedia

    en.wikipedia.org/wiki/American_wire_gauge

    However, AWG is dissimilar to IEC 60228, the metric wire-size standard used in most parts of the world, based directly on the wire cross-section area (in square millimetres, mm 2). The AWG tables are for a single, solid and round conductor. The AWG of a stranded wire is determined by the cross-sectional area of the equivalent solid conductor.

  4. Ammeter - Wikipedia

    en.wikipedia.org/wiki/Ammeter

    An ammeter (abbreviation of ampere meter) is an instrument used to measure the current in a circuit. Electric currents are measured in amperes (A), hence the name. For direct measurement, the ammeter is connected in series with the circuit in which the current is to be measured.

  5. Ampere-turn - Wikipedia

    en.wikipedia.org/wiki/Ampere-turn

    The ampere-turn (symbol A⋅t) is the MKS (metre–kilogram–second) unit of magnetomotive force (MMF), represented by a direct current of one ampere flowing in a single-turn loop. [1] Turns refers to the winding number of an electrical conductor composing an electromagnetic coil .

  6. Pilot-operated relief valve - Wikipedia

    en.wikipedia.org/wiki/Pilot-operated_relief_valve

    At set pressure the valve snaps to full lift. This can be quite violent on large pipes with significant pressure. The pressure has to drop below the set pressure in order for the piston to reseat (see blowdown in relief valve article). Modulating The pilot is designed to open gradually, so that less of the system fluid is lost during each ...

  8. Henry (unit) - Wikipedia

    en.wikipedia.org/wiki/Henry_(unit)

    The henry (symbol: H) is the unit of electrical inductance in the International System of Units (SI). [1] If a current of 1 ampere flowing through a coil produces flux linkage of 1 weber turn, that coil has a self-inductance of 1 henry.‌ The unit is named after Joseph Henry (1797–1878), the American scientist who discovered electromagnetic induction independently of and at about the same ...
