admittance
electronics
Quick Summary
Admittance is the reciprocal of electrical impedance. Electrical impedance is the total opposition a circuit presents to electric current, encompassing both resistance and reactance. Resistance occurs due to charged particle collisions within a conductor, while reactance arises from changing electric and magnetic fields in alternating current circuits. Impedance is measured in ohms, and its reciprocal, admittance, is expressed in mhos (or siemens).12
