Answer 1

Answer:

A wire that provides an electrical connection to the ground. The purpose of an earth wire may be to protect against accidental electric shock (by providing a route for current that would otherwise pass through a person), or against possible damage (by limiting the increase in voltage that can occur in a device).

Answer 2

$\huge\mathcal\color{purple} Answer :-$

Earth wire prevents Electric shocks. It is connected to the electrical cable of an appliance to prevents electric shocks. Actually it has very low resistance and allows current to pass through it easily. Whenever there is a fault in an Appliance and if then a person touches it he might get a massive Electric shock. But the earth wire having lower resistance than the body allows the current to pass through it. It is so because the current has the tendency to pass through low resistance body. It thus direct the current towards earth and the person is saved from massive Electric shock which may lead to his death.
