Rs = | Zs | cos Θ
Xs = | Zs | sin Θ
Xs / Rs = tan Θ
There are two types of reactance. One is inductive reactance –
X
L
, and the other is capacitive reactance – X
C
.
If Θ > 0, the reactance is inductive. If Θ < 0, the reactance is
capacitive.
The inductive and capacitive reactances ( X
L
and X
C
) can be
defined as:
X
L
= 2 π ƒ L
X
C
=1÷(2 π ƒ C)
Where:
L = Inductance
C = Capacitance
ƒ= signal frequency)
