Although calculators and computers can now easily give answers to the problems the Smith chart was designed to solve, this great chart still remains a valuable tool.

Admittance of an AC circuit is the reciprocal of its impedance. Using the impedance value one can easily derive the Admittance values of the circuit. Admittance 'Y' can be measured as Y = 1/Z. where 'Z' is the impedance, Z = R+jX. So, admittance 'Y' can be written as, Y = 1/R+jX. Thus, the formula of Admittance when derived from ...method.
