Inductive coupling with/and AC?
Several things I wanted to know, but couldn't find;
If 2 AC outputs are of the same amplitude, but of different frequency, will one necessarily be higher in power?
In a conventional transformer, (not resonant) does a higher frequency allow for higher efficiency coupling? Does this change if the transformer is resonant?
Is a 'standard' transformer more efficient than a resonant one at a very close range? (Provided that frequency, power, etc. are all the same?)
And lastly, does the resonant frequency of a resonant inductive coupling circuit affect the frequency at which it couples?
(did that all make sense?)
