The formula to calculate the Admittance is:
\[ Y = \frac{1}{Z} \]
Where:
Let's say the impedance is 50 Ohms. The admittance would be calculated as follows:
\[ Y = \frac{1}{50} = 0.02 \text{ Siemens} \]
So, the admittance is 0.02 Siemens.
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).
