  2. Galvanometer - Wikipedia

    en.wikipedia.org/wiki/Galvanometer

    An early D'Arsonval galvanometer showing magnet and rotating coil. A galvanometer is an electromechanical measuring instrument for electric current.Early galvanometers were uncalibrated, but improved versions, called ammeters, were calibrated and could measure the flow of current more precisely.

  3. Chart recorder - Wikipedia

    en.wikipedia.org/wiki/Chart_recorder

    Many types of chart recorders use a galvanometer to drive the marking device. A light coil of wire suspended in the magnetic field of a permanent magnet deflects in proportion to the current through it; instead of the pointer and scale of a direct-reading meter, the recorder deflects a pen or other marking device.

  4. American wire gauge - Wikipedia

    en.wikipedia.org/wiki/American_wire_gauge

    Wire sized 1 AWG is referred to as "one gauge" or "No. 1" wire; similarly, thinner sizes are pronounced "x gauge" or "No. x" wire, where x is the positive-integer AWG number. Consecutive AWG wire sizes thicker than No. 1 wire are designated by the number of zeros: No. 0, often written 1/0 and referred to as "one aught" wire

  5. Wire gauge - Wikipedia

    en.wikipedia.org/wiki/Wire_gauge

    Each notch is stamped with a number, and the wire or sheet, which just fits a given notch, is stated to be of, say, No. 10, 11, 12, etc., of the wire gauge. The circular forms of wire gauge measurement devices are the most popular, and are generally 3 + 3 ⁄ 4 inches (95 mm) in diameter, with thirty-six notches; many have the decimal ...

  9. Fleming's right-hand rule - Wikipedia

    en.wikipedia.org/wiki/Fleming's_right-hand_rule

    When a conductor such as a wire attached to a circuit moves through a magnetic field, an electric current is induced in the wire due to Faraday's law of induction. The current in the wire can have two possible directions. Fleming's right-hand rule gives which direction the current flows.
