      Yes. At a fraction of a volt it doesn't penetrate the dead skin. At a   
   higher voltage it does. 24VAC is the limit for low voltage wiring because of   
   this after you pass that limit you will start to feel a tingle. Keep raising   
   it will cause electrocution.   
    I was outside my business one day. I watched a squirrel bite into the primary   
   7200 volt line. He exploded and took out about 12 blocks of downtown Eustis,   
   Florida for several hours. They had to clean up its remains, and replace   
   damaged hardware before    
   they could replace a fuse on the primary side. Once the voltage is high enough   
   to penetrate the sin, the resistance drops down into the hundred ohms range.
