| admittance (ād-mĭt'ns) Pronunciation Key
A measure of the ability of a circuit or component to allow current flow when exposed to AC voltages (its AC conductance). It is equal to the reciprocal of the impedance of the circuit, just as conductivity is equal to the reciprocal of resistance, and is similarly measured in mhos. |
