  • Page 109 ◆ Resistance (R) and Conductance (G) The resistance is a measure of the difficulty to pass an electric current through that conductor. The SI unit of resistance is the “ohm” (Ω). The inverse quantity is electrical conductance, and this is the ease with which an electric current passes through a circuit.

  • Page 111 ◆ Inductance (L) Inductance is the property of an electrical conductor by which a change in current through it induces an electromotive force (EMF) in both the conductor itself and in any nearby conductors by mutual inductance. In the SI system, the measurement unit for inductance is the Henry (with the unit symbol H).
  • Page 112 ◆ Reactance (X) and Susceptance (B) In AC circuit analysis, reactance is represented by the capital letter “X” which is the imaginary a part of complex impedance. Reactance is the opposition of a circuit element to a change in the current or voltage, due to that element's inductance or capacitance which is similar to the opposition of resistance to current in a DC circuit.
  • Page 113 ◆ Impedance (Z) and Admittance (Y) The impedance covers oppositions in AC circuits including resistance, inductance, and capacitance and is measured in units of Ohm (Ω). In electrical engineering, admittance covers both conductance and susceptance and is the reciprocal of impedance. It is measured in units of Siemens (S).
  • Page 114 ◆ Quality factor (Q) and Dissipation factor (D) The quality factor measures energies consumed by relative frequency. In general, the better a circuit's quality factor the better its selectivity. The dissipation factor is the reciprocal of quality factor. It is the signal angle loss by a capacitor (or inductor) and acting frequency at a fixed temperature.
