Answers

advantage of the third wire of earth connection in domestic electric appliances are: 
The danger when using dangerous voltages in domestic equipment is that accidental malfunctions will result in users being elecrocuted. The process of electrocution is that a person who is connected to ground by simply standing on a sufficiently conductive floor becomes connected to the "hot" side of the supply. As most people exhibit approximately 5,000 to 10,000 ohms resistance, a current of 23 to 46 milliamperes will flow through the person if the voltage is 115 volts.
