1.	What is earth wire ..? How it works in our domestic circuit
Answer» The earth wire gives a safe route for the current if the live wire touches the outer casing. Livewire is A wire carrying electric current. The metallic body is connected to the earth wire, which provides a low resistance-conducting path for the current. It ensures that any leakage of current of the metallic body the appliance will flow to the earth only and the user may not get a severe shock. we connect the\xa0earth wire\xa0to metal casing of electrical appliances by using three pin plug. If by chance, live\xa0wiretouches any metal case parts of appliances then current passes directly to\xa0earth. hence\xa0earthing\xa0is used as safety measure to prevent shock from metal objects.
