Question

What is the addmitance of a 7 ohm inductor?

Answer 1

1/r or 1/7 see http://www.rfcafe.com/references/electri...

Answer 2

Admittance is the reciprocal of impedance. The impedance of an inductance L at angular frequency w is Z = jwL, so its admittance is Y = 1/(jwL) = -j/(wL).

By a "7 ohm inductor" I assume you mean one that has an impedance of magnitude |Z| = 7 ohms at a particular frequency. The admittance is then of magnitude |Y| = 1/7 ohm at that frequency.
