Most of the time cords are covered by insulation. The insulation keeps the wires from touching. If the insulation becomes damaged, this creates an area of low resistance and if a large current goes through this area, there will be rapid over-heating and possibly result in a fire. Repair damaged insulation immediately. Water and electricity are always a dangerous combination.
Water conducts electricity.
You should never use electric appliances or touch sources of electricity such as light bulbs, sockets, or outlets while in contact with water. Any wire connected to a voltage is called a live wire. You should never touch a live wire. If you do, your body will become part of a circuit. A large current will flow through you and into the ground.
