Lets put this into perspective.
240v supply with a kettle with a resistance of say 26ohms
ohms law = V/R=I
Therfore 240volts/26ohms = 9amps
The man in the video.
The human body has a resistance of about 50,000 ohms(this varies from person to person)
The voltage on the site says the main line voltage is either 1.5kv DC or 25kV AC.
We can calculate both figures using ohms law.
1 500volts/50 000ohms = .3amps <--- Thats right, less than one amp.
25 000volts/50 000 = .5amps <--- Also less that one amp.
The interesting thing is his power output
When charcol gary is drawing .3amp his power output is 45watts <--- Comparable to a light globe
When charcol gary is drawing .5amp his power output is 12500watts <--- comparable to an air conditioning unit for a small house.
Take this into account
.001amps to 0.01 = threshold of sensation
.01amp to .1amp = painful shock, cannot let go, muscular paralysis, severe shock, breathing difficultys
0.1amps to 0.2 amps = death
0.2amps to 1.0amp = severe burning.
May i remind all to be careful around electricity please. may i also point out that his arms go rigid.
