Impedance(Z) / Admittance(Y) / Conductance(G) / Susceptance(B) / Resistance(R) / Reactance(X)

* Passive elements - V = RI - V = jwLI - V=1/jwC (V, I -> phasor) Z = V / I Z is a frequency-dependent quantity known as impedance(ohms) Z = R + jX (R : resistance, X : reactance) Y = 1 / Z = I / V The admittance Y is the reciprocal of impedance, measured in siemens(S) Y = G + jB (G : conductance, B : susceptance) G + jB = 1 / (R + jX) Thus, G = R / (R^2 + X^2), B = - X / (R^2 + X^2)...
