Microtest 6632 Series - Impedance (Z) and Admittance (Y)

94
 Impedance (Z) and Admittance (Y)
The impedance covers oppositions in AC circuits including resistance,
inductance, and capacitance and is measured in units of Ohm (Ω).
In electrical engineering, admittance covers both conductance and
susceptance and is the reciprocal of impedance. It is measured in units of
Siemens (S).
