The admittance model represents a parallel connection of a conductor and either a capacitor or inductor.

The linear admittance connects the voltage v with the current i by i = Y*v. The resistive component is modeled temperature dependent, so the real part G_actual = real(Y) is determined from the actual operating temperature and the reference input conductance real(Y_ref). A conditional heat port is considered. The reactive component B_actual = imag(Y) is equal to imag(Y_ref) if frequencyDependent = false. Frequency dependency is considered by frequencyDependent = true, distinguishing two cases:

(a) imag(Y_ref) > 0: capacitive case

The actual susceptance B_actual is proportional to f/f_ref

(b) imag(Y_ref) < 0: inductive case

The actual susceptance B_actual is proportional to f_ref/f
