This is probably a very easy question but I have been wondering for a while and can't seem to find a definitive answer anywhere. If you touch one hand to the positive lead on a 12v car battery and are grounded on something not connected to the negative terminal on the same battery, will you get a shock? My initial thought was that if you are standing on the ground which has a voltage of around 0(correct?) and initiate a potential difference by touching the 12v lead, current will result which produces a shock. This just doesn't seem right though for some reason. Please clarify this. Thanks.
