Claim:
1. A power transmission system comprising: a power transmitting apparatus including: a power receiving apparatus including: wherein, when the pair of second electrodes are positioned to face the pair of first electrodes, the series resonant circuit and the parallel resonant circuit form a composite resonant circuit through compound capacitance between the pair of first electrodes and the pair of second electrodes, wherein a configuration component of the composite resonant circuit has an impedance such that when the pair of second electrodes are facing the pair of first electrodes in a predetermined state with the compound capacitance having a maximum value, a resonant frequency of the composite resonant circuit is higher in a first state of the power receiving apparatus than a second state of the power receiving apparatus, and wherein the first state of the power receiving apparatus is when inputs of the load circuit are short-circuited and the second state of the power receiving apparatus is when the inputs of the load circuit are open.
