IMO? Nothing. Electrical resistance has to do with the physical properties of your physical body- how much electricity can go through your skin or over it (galvanic response) or any other type of resistance to current through your body. Your bones will have different resistance than, say the blood, and the cells will have a different resistance than either. The aura can be many things, but I don't think it's electricity as we know it- if it were it would be easy to detect and part of accepted science. But it isn't. But then again, I don't know what it is either- only that some people can see them, and others don't.
