This admittance calculator finds the admittance Y — the reciprocal of impedance — from impedance, or from conductance and susceptance. Enter the values above.
Formulas
Y = 1 ÷ Z Y = G + jB |Y| = √(G² + B²)
- G — conductance, B — susceptance (siemens)
Example
Z = 50 Ω (resistive): Y = 1 ÷ 50 = 0.02 S.

Frequently Asked Questions
What is admittance?
It is the reciprocal of impedance, measuring how easily AC flows. It combines conductance and susceptance.
How do I calculate admittance?
Take the reciprocal of impedance: Y = 1 / Z. For a 50-ohm resistor, Y is 0.02 siemens.
What are conductance and susceptance?
Conductance is the real part of admittance, susceptance the imaginary part, both in siemens.
