Admittance

The current that flows when one volt is applied. [mho] Admittance is the reciprocal of impedance.

• At short circuit resonance, a high admittance (low impedance) is one indicator of a properly designed stack, whereas a low admittance indicates a lossy stack.
• At open circuit resonance, a low admittance (high impedance) is one indicator of a properly designed stack, whereas a high admittance indicates a lossy stack.
