Wet Location Body Resistance

mapj1:

Some background reading . I suggest not to be read just before bedtime or if you are about to eat and are of a nervous nature.
here Intro to what happens in shock from NIH   


 Model of skin as an RC network.    And test cells of 1cm square sections of post mortem skin tested and getting ~ 10k ohms per sq cm of contact area with salt solution as the electrodes on the 2  sides.

the 1956 work by Dalziel "Effects of electrical shock on man"    Tries to define a time/current curve for electrocution,

Another one by the same author with pictures of folk grimacing holding electrodes.  looks "fun" but I reckon you could not do these tests nowadays.

This one includes figures for conductivity of various internal organs and RC models for things like minced lung. Not sure how relevant that is but the conductivity is of order 100-500 ohm-cm for common organs. So the internal path once the skin is broken through is lower resistance  - the skin is the main resistance.

Grimnes S. Dielectric breakdown of human skin in vivo. Med Biol Eng Comp.  is also worth a read, but no copies seem to have escaped onto the internet, sadly.

Thanks


Reading through I'm getting about 500 ohms wet, 1500 ohms worse case dry.
