1.2. Impedance parameter definition
According to the different measuring signal of impedance meter,It can be separated
DC and AC impedance meter。The popular multimeter in market is a DC resistance
meter;The MPT LCR01A/B is an AC/DC impedance meter。For electronic Circuit,
component and material,impedance is an important parameter。
In engineering,vector is used to express impedance,It analysed real part Resistance(R)
and imagine part reactance(X) ; And the polar express impedance(Magnitude) and
Theta(Phase)。Diagrams below show the relation。

Z = Rs+jXs =∣Z∣∠θ (Ω)
Rs =∣Z∣Cosθ ∣Z∣= Rs 2 + Xs

Xs =∣Z∣Sinθ θ = Tan -1 (Xs/Rs)
Z:Impedance Rs:Resistance Xs:Reactance Ω:Unit Ohm

Reactance can be separated as(Inductive) XL and(Capacitive) X
C。The definition as:
X
L =ωL=2π fL
and
L:Inductance (H)
C:Capacitance (F)
f:Frequency (Hz)
X
C =(ωC) -1
=(2π fC) -1
Additional,other parameters are attached to passive component,Quality factor(Q) and
Dissipation Factor(D)。Both are defined the purity of reactance,that is the energy
storage(reactance) and the energy consumption(resistance)ratio,defined as follow:
Q=D -1 = (tanδ ) -1
=∣Xs∣.Rs-1=ω.Ls.Rs-1=(ω.Cs.Rs) -1
=∣B∣.G-1
= Rp.∣Xs∣-1
=Rp.(ω.Lp) -1
=ω.Cp.Rp
Quality factor is applied on inductive components,and Dissipation factor is applied
on capacitive components。Both are reciprocal each other。
Traditional,component can be analysed as series equivalent and parallel equivalent。
Both defined as follow。
