Wireless electricity transfer through electric resonance

-Input Signal: 188 KHz, square wave AC, 20 Volts Peak to Peak (Vpp) or 10 Volts Root Main Square (RMS) from a Signal Generator

-Capacitors: Unpolarized, in parallel with coil (not mandatory to have capacitor at the transmitter, but increases slightly led brightness)

-Coils: length=5 meters, diameter=1 mm, single wire, single layer, cylinder diameter= 12 cm, speaker cable for both transmitter & receiver (coil shape matters !!!)

-LED: 1 bright 3Volt white LED at the receiver coil

-Resonance occurs at more frequencies: 16, 20, 26, 36, 59, 188 KHZ (led is brightest at 188 KHz)

that is a very in efficient energy transfer there is a lot of it wasted

[furulevi]

@WatchmenDrManhattan I haven't measured the input or the output power, but the signal generator gives a very low amperage, that's why the led has to use 20 volts. Even a normal incandescent 3V light bulb is lit up with around 20V from the signal generator.

Hy, I'm trying to do the same as you, but I would like to ask you if you know some fisic law or something to calculate the resonance frequency, the capacitor value or the cable lengh.

[furulevi]

@TomasArJ Just google "resonance calculator" there are many online programs for that, I haven't calculated anything, I just experimented and found some useful frequencies...

hi i really like your video actually i am trying to do something similar, so what capacitors did you use? how many f are?

[furulevi]

@m4dr4abbit Unpolarized capacitors are used (polarized ones don't work in this setup), I don't know exactly their value, but different capacitor values will produce resonance at different frequencies!

jai ho!!

@furulevi thanks this video was really helpfull it help me to get an a on my final proyect

[bronzinah]

@pjckac1 if the coils are identical as furulevi said, it can't be a tranform. Thor is stupid. (but some people just try to guess meanwhile others know what they are talking about)

TO:ThorTheCommenter

It always amazes me that there is always someone that leaves a negative comment including the vulgar language because of a mental situation going on in their life being released to others to spread negative energy.
