Earth (Ground)

 

 

The earth connection must be used in electrical and electronics circuits.  Because earth is zero potential or ‘zero Volt’. So that when current of the circuit is high then it is follow in to the high potential to zero potential. Ground is used for safety of  circuits from fire accident and short circuit.
