  • A
    Susceptance
  • B
    Conductance
  • C
    Admittance
  • D
    Transconductance

Answer

  1. Admittance

Explanation:

Impedance is the opposition a circuit presents to a current when a voltage is applied.

Admittance is a measure of how easily a circuit or device will allow a current to flow.

Admittance is defined as $\text{Y}=\frac{1}{\text{Z}}$

where Z is the impedance of the circuit.
