The car of a man driving home from work in a rain storm stalls due to faulty ignition cables where there is a crack in the insulation. He attempts to fix the problem by inspecting his electrical system. While holding onto ground with one wet hand he touches the positive battery terminal with his other wet hand. The car battery operates at 12 volts with the negative terminal attached to ground. What current flows through his body? Is he at risk of being electrocuted?
