When a wire connecting circuit is connected to earth than it is known as earthing, if you touch circuit actually you behave like that wire and entire charge passes through your body and you will feel shock. Human body is good conductor of electricity.

3.A cat's skin acquires positive charge when rubbed with ebonite rod.
