Hi, coleagues. I'd like to hear others' opinions regarding these: a. why we don't get electrified when just touching an exposed conducting wire, despite the fact that current does flow thru us ? (while the touching body is kept isolated and unearthed). b. when an exposed wire is being touched by a bare hand (in principle), can the hand lit a bulb while unearthed ? c. the danger in touching a wire while earthed is due the immense current due to the voltage falling on the body, according to [[Ohm's law]] (since the voltage can reach hundreds to thousands of Volts). Does this explanation describe the situation, correctly & fully ? Thank you.
