Formula to calculate the impedance (Z) and admittance (Y=1/Z)
Impedance measures the overall inhibiton by the two terminals to the AC. The
admittance and the impedance are reciprocal. The former measures the physical quantity
of the degree of ease for AC current to flow through the two terminals.

Formula to calculate the qualify factor (Q) and dissipation factor (D)
The quality factor and dissipation factor are reciprocal. They are used to measure the
physical quantity of the energy loss rate at the measurement frequency. Low power
consumption: high Q, low D; high energy consumption: low Q, high D.
Quality factor (Q)
Dissipation factor (D)
