It is all to do with current and the path it takes. Cattle fences have a 
limited amount of current and it is dc. Domestic supplies are ac and 
although the current is limited it is in the region of amps. It is the 
current that kills you. More importantly id the current passed through 
your heart the ac component disrupts the electrical signals to the heart 
and in the heart so it starts to fibrillate that is the signals to 

better as it is his subject.
