E5B12
What is admittance?
- A.The inverse of impedance (correct answer)
- B.The term for the gain of a field effect transistor
- C.The inverse of reactance
- D.The term for the on-impedance of a field effect transistor
WhyAdmittance is the inverse of impedance. Admittance is defined as the inverse of impedance, the AC equivalent of how conductance is the inverse of resistance in a DC circuit, answer A. It has nothing to do with field effect transistor gain or on-resistance, those are unrelated semiconductor parameters that happen to share some vocabulary but not this specific meaning.
