The act of giving possession of a copyhold estate. Bouvier.

[Sarah]

The inverse of impedance. Usually denoted as Y in electrical equations, or 1/Z, Z being impedance. The unit value of admittance is commonly dubbed mhos (backwards spelling of ohms.) It is a measure of the lack of impedance in a circuit, system of circuits or a specific conductor. A short circuit should, ideally, have an admittance of infinity. An open circuit will have an ideal admittance of 0 mhos.
