  2. Electrical measurements - Wikipedia

    en.wikipedia.org/wiki/Electrical_measurements

    Electrical measurements are the methods, devices and calculations used to measure electrical quantities. Measurement of electrical quantities may be done to measure electrical parameters of a system. Using transducers, physical properties such as temperature, pressure, flow, force

    Displays waveform of a signal, allows measurement of frequency, timing, peak excursion, offset, ... Psophometer: Measures AF signal level and noise Q meter: Measures Q factor of the RF circuits Tachometer: Measures speed of motors Signal analyzer: Measures both the amplitude and the modulation of a RF signal Signal generator

  4. Electrical susceptance - Wikipedia

    en.wikipedia.org/wiki/Electrical_susceptance

    In electrical engineering, susceptance (B) is the imaginary part of admittance (Y = G + jB), where the real part is conductance (G). The reciprocal of admittance is impedance (Z = R + jX), where the imaginary part is reactance (X) and the real part is resistance (R). In SI units, susceptance is measured in siemens (S).

    The first includes all the older gauge measurements, notably the Birmingham gauge (B.W.G. or Stubs) and the Lancashire. The origin of the B.W.G. is obscure. The origin of the B.W.G. is obscure. The numbers of wire were in common use earlier than 1735 when the measurements were officially defined. [ 1 ]
