Modern Wireless Power
Resonance in terms of sound waves is defined as the frequency in which an object, given its shape and size naturally vibrates. In a wireless power transfer using coils, the resonant frequency is determined by multiplying the capacitance value of the plates attached to the ends of the coil and the inductance value of the coil. Using this set-up, the coil would resonate whenever a current passes through the coilhttp://tw.myblog.yahoo.com/jw!6ll5UeGCFQUo00va6Dk_C4Sv/article?mid=856&prev=859&next=843&l=f&fid=8 靜磁發電機
