Admittance(y) :
1/z It is the reciprocal of impedance and is called Admittance.
Conductances (G) :
It is the ratio of Resistance and square of impedance.
it is denoted by G.
Its unit is Siemens.
G = R/z^2 .
Suseptance(B) :
It is the ratio of Resistance (X) and scequre of impidance(Z).
It is denoted by B.
It's major in Siemens.
BL = 1/XL , BC = 1/XC .
