Admittance is the ease with which alternating current flows within a circuit and is measured in Siemens [S]. Admittance is a reciprocal of impedance. eg Admittance = 1 / Impedance.

Formula

Y = 1 / ( R2 + X2 )0.5 X = ( ( 1 / Y )2 - R2 )0.5 R = ( ( 1 / Y )2 - X2 )0.5

Y = Admittance (siemens [S]) R = Resistance (ohms [W]) X = Reactance (ohms [W])
