Impedance (Z):
It is the opposition offered by an AC circuit to the flow of AC current.
It is denoted by the letter ‘Z’. Its unit is Ohm.

Impedance (Z)=VI Impedance in complex quantity:
Z=R+jX
Where,
Real part :
R - Resistance Imaginary part:
X - Reactance.

Inductive Reactance (XL):
The opposition offered by an inductance to current flow is called inductive reactance. It is denoted by the letter XL and its unit is Ohm .
Inductive Reactance XL =2πfL

Capacitive Reactance (XC)
The opposition offered by a capacitance to current flow is called capacitive reactance.

It is denoted by the letter XC and its unit is ohm ѐ=1ωC=12πfC

Admittance (Y):
It is defined as the reciprocal of impedance.
It is represented by the letter ‘Y’ and its unit is mho (Ʊ) or siemen.

Conductance (G):
It is defined as the reciprocal of resistance. It is represented by the letter G and its unit is mho (Ʊ) or siemen.
