The total effective resistance of an LCR (inductor-capacitor-resistor) AC circuit is known as impedance, which is a complex quantity comprising the actual resistance and the reactances due to the inductance and capacitance. However, the reciprocal of impedance is called admittance. Admittance is a measure of how easily a circuit will allow electrical current to flow. In mathematical terms, if the impedance Z is a complex number represented as : Z=R+jX where R is the resistance, X is the reactance, and j is the imaginary unit. The admittance Y is the reciprocal of the impedance : Y=‌
