There are two different types of reactance: Inductive (X
L
) and Capacitive (X
C
). It can be defined
as follows:
For components, the quality factor (Q) serves as a measurement of the reactance purity. In the
real world, there is always some associated resistance that dissipates power, decreasing the
amount of energy that can be recovered. The quality factor can be defined as the ratio of the
stored energy (reactance) and the dissipated energy (resistance). Q is generally associated with
inductors and D (dissipation factor) for capacitors. Below shows the relationships between
these parameters:
