Almost all the fish the researchers caught had parts of their tails bitten off, which eventually regenerate. For those fish with a biphasic current, the negative part of the charge comes from the tail. As a result, the researchers speculate, switching to a monophasic signal may help them to communicate and electrolocate in spite of tail damage.https://phys.org/news/2013-10-electric-fish-ac-dc.html
So in the John Chang study - they tried to use his "negative part of the charge" as from his perineum - but they still couldn't get a volt signal. Why? It wasn't till he started lighting up the LED bulb that they got a signal.

He says what he does is no different than an electric eel.
So they do get a reading of 300 millivolts or 380 millivolts and the person says he can feel it through his whole body.
Maybe that is milliamps? they say it's a volt reader so I assume it's volts.
OK I notice something very fascinating - when the video says
"the needle still isn't moving" - JOhn Chang is holding the negative needle in his left hand!
So then in the next testing John chang is holding the positive needle is his left hand and they are getting a volt reading!
I can't tell for sure. Maybe the positive needle is still being put against his stomach.
Yeah now he has the negative needle in his right hand and the positive is to his stomach.
He says the "positive is his navel chakra"
Right - so the right hand is holding the negative needle! And in Daoism for males the right hand is yin - and so now they are finally getting a volt reading! Cool.
Each LED need 3 voltsSo he says John Chang lights up the LED based on "intensity of current."

the driver needs some means to limit the current draw by the LED, because small variations in voltage may lead to large variations in current as mentioned before, the device limiting the current will also drop some voltage, around 1 volt typical, resulting a voltage of 10 volts at the output of the driver.
the type of LEDs used (the voltage drop across the LED will depend on its doping - Red has the lowest voltage drop and Blue the highest)So as I posted in a previous blog post - the voltage is then based on the wavelength of the light of the energy.
And it's in milliamps for power.
20 milliamps
