Enter the Impedance into the calculator to determine the Admittance. This calculator can also evaluate the impedance given the admittance.

## Admittance Formula

The following formula is used to calculate the Admittance (Y) of an electrical circuit.

Y = 1 / Z

Variables:

• Y is the Admittance (Siemens) Z is the Impedance (Ohms)

To calculate the Admittance, take the reciprocal of the Impedance. This means dividing 1 by the value of the Impedance.

## What is Admittance?

Admittance is a measure of how easily a circuit or device allows an electric current to flow through it. It is the reciprocal of impedance, which measures the opposition to current flow. Admittance is typically represented by the letter ‘Y’ and is measured in siemens (S). It includes both conductance (real part of admittance, which allows current flow without phase shift) and susceptance (imaginary part of admittance, which allows current flow with phase shift).

## How to Calculate Admittance?

The following steps outline how to calculate the Admittance using the formula Y = 1 / Z.

1. First, determine the value of the Impedance (Z) in Ohms.
2. Next, use the formula Y = 1 / Z to calculate the Admittance (Y) in Siemens.
3. Finally, you have calculated the Admittance (Y).
