Admittance

The admittance from the Latin " admittere " to German "assume", even complex conductance, is in electrical engineering, the reciprocal of the impedance:

The admittance is a complex quantity, which consists of the real part, the conductance ( conductance ) G and the imaginary, the susceptance ( susceptance ) B. The amount of the admittance is called the admittance Y.

The SI unit of admittance is given in S ( Siemens).

For a complex-valued impedance is thus given by:

With or

At the result of the above calculation it is seen that the conductance and susceptance generally does not result from the reciprocal of the real and imaginary part of the impedance.

In scientific notation, one can write:
