What's the Difference Between Impedance and Admittance?

Admittance is the reciprocal (inverse) of impedance, akin to how conductance and resistance are related. The SI unit of admittance is the siemens (symbol S). ... When looking at admittance vs impedance, admittance is the inverse (i.e. the reciprocal) of impedance. Therefore it has the opposite function of impedance.

Why do we use admittance instead of impedance?

Admittance is the opposite of impedance and as such, is best described as how easily current can flow when voltage is applied, or how much current is admitted through the circuit. If impedance is more akin to current friction, then admittance would be comparable to ice or a slippery surface.

Is the impedance increases the admittance?

Explanation: As the impedance increases, the admittance decreases because admittance is equal to 1/impedance.
