Apparently the worst is being grounded with one hand, and touching the a.c. with the other, because the path goes right through your heart area. Whether your hands were dry or moist would make an enormous difference in the amount of current - easy to check this out yourself with a 9V battery and a digital VOM meter ;-) ..................N<br></div><div class="gmail_extra"><br><div class="gmail_quote"><div><div>On Sat, Feb 7, 2015 at 2:30 PM, Benjamin Pratt <span dir="ltr"><<a href="mailto:benjamin.g.pratt@gmail.com" target="_blank">benjamin.g.pratt@gmail.com</a>></span> wrote:<br></div></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div><div dir="ltr">All- <div>Quite a bit of googling has not answered my question so I thought I'd ask here. If I shock myself on 110v current while ungrounded (wearing rubber soled shoes on a wood floor for instance), is it dangerous or harmful to my health? It doesn't really bother me much but many people seem to think it is really dangerous and harmful. I try to avoid being shocked, and have never been shocked while grounded, but I have been shocked while ungrounded numerous times without any lasting ill effects.</div><div>Ben<br clear="all"><div><div><div dir="ltr"><br><div><br></div><br>b e n j a m i n p r a t t<div><br>professor art+design</div><div>the university of wisconsin stout</div></div></div></div>
