The real part of the admittance of an alternating-current circuit. The admittance Y of an alternating-current circuit is a complex number given by Eq. (1).
1. Y = G + jB
The real part G is the conductance. The units of conductance, like those of admittance, are called siemens or mhos. Conductance is a positive quantity. The conductance of a resistor R is given by Eq. (2).
2. G = {1\over R}

In general the conductance of a circuit may depend on the capacitors and inductors in the circuit as well as on the resistors. For example, the circuit in the illustration has impedance at frequency ω given by Eq. (3) and admittance given by Eq. (4), so that the conductance, given by Eq. (5), depends on
3. Z = R + jL\omega

4. Y = {1\over R + jL\omega }

5. G = {R\over R^2 + L^2\omega ^2}
the inductance L as well as the resistance R. See also Admittance; Electrical impedance.
