24. Impedance and admittance

The Periodic Table of the Elements is a fundamental basis for all engineering.
It is the basic information of Impedance and admittance those are fundamentals of AC circuit. Impedance extends the concept of resistance, admittance does the concept of conductance to AC circuit.
