The imaginary 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). The imaginary part, B, is the susceptance.
In general, the susceptance of a circuit may depend on the resistors as well as the capacitors and inductors. For example, the circuit in the illustration has impedance given by Eq. (4) and admittance given by Eq. (5), so that the susceptance, given by Eq. (6), depends on the resistor R as well as the inductor L. (4) (5) (6) See Admittance, Electrical impedance
