which one to choose series LC or parallel LC resonant circuit?

[JUAK]

hello,
My task is to transmit electricity via resonant inductive coupling using only one transmitter coil and one receiver coil..
I do not know which one is better to use for my transmitter circuit and receiver circuit, series LC or parallel LC as to make my coil resonate at specific frequency..

I would appreciate an answer with a brief explanation..
Thx ..

..i found a book tells that parallel resonance is used for transmitter and receiver circuits.
But no explanation about that..
anyone plz?

I can never remember which way it is, I think parallel gives high impendance at resonance with high voltage and series gives low impedance at resonance with lower voltage, I'm sure someone will be along soon with the answer.

I have a small collection of vintage valve radios, to test them I have a home bashed transmitter for broadcast am, it has a parallel lc tank circuit which performs 2 jobs, it produces a reasonable clean output from a squarewave input, and the inductor is also the aerial (1 meter square of ally tig welding rods), one end is fed with a radio freq squarewave from a crystal osc and the other end comes from a audio power amp chip.

Local oscillators in tranny radios before they went direct synthesis commonly used parallel oscillators.

I'd reccomend parallel, heres some interesting reading for you :
