Impedance and admittance.

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.
