Electrical sockets supply a flow of current which comes out of one pin of a socket, called "Live", runs through an electrical device, and returns through the other pin "Neutral." In many countries, such as USA, India and others, the "Neutral" is also connected to the earth (via a rod driven into the soil). If a person touches a bare "live" wire, current can travel through the body to any part (like another hand or the bare feet) connected directly or indirectly to the earth, such as through metal such as plumbing pipes or through moist tiles or a bathtub full of water where the water acts as a conductor. Pure water is a poor conductor but in the kitchen or bathroom it is usually salty or soapy which increases the conductivity; but no matter, since it takes so little current to kill a person, even a poor conductor can result in a lethal shock.
