電阻 電容 電感: -ance

//===
resistance, conductance: conductance = 1/resistance for "pure resistor"(passive load).
capacitance, inductance
capacitor, inductor
capacitive, inductive

//===
impedance = resistance + j*reactance
Z= R + jX
阻抗= 電阻 + 電抗

admittance= conductance + j*susceptance
Y= G + jB
導納= 電導 + 電納

"The phase of the complex impedance is the phase shift by which the current is ahead of the voltage."
