What is the term for the inverse of impedance?
- A.Conductance
- B.Susceptance
- C.Reluctance
- D.Admittance (correct answer)
WhyAdmittance is the term for the inverse of impedance. Admittance is defined as the mathematical inverse of impedance, the AC analog of how conductance is the inverse of resistance in a DC circuit, answer D. Conductance and susceptance are the real and imaginary parts that make up admittance rather than admittance itself, and reluctance is an unrelated magnetic-circuit quantity, so A, B, and C don't fit the definition asked for.
