Positive sign is for an inductive circuit and negative sign is for a capacitive
circuit.

Admittance

Rationalizing the above expression,

Figure 3.31 Impedance and admittance triangles

Where G = Conductance

and B = Susceptance

B is negative if the circuit is inductive and B is positive if the circuit is
capacitive. The impedance triangle and admittance triangle for the circuit

have been shown in Fig. 3.31.
