Explain why a charged body loses its charge if we touch it with our hand.

Hint: The process of transferring the immediate discharge of the electricity onto the earth with the help of the low resistance wire is known as earthing electrical attachment. The electrical earthing is completed by connecting the non-current carrying a part of the equipment or neutral of providing the system to the bottom.

Answer
Mostly, the galvanized iron is employed for the attachment. The attachment provides the easy path to the outpouring current. The short-circuit current of the equipment passes to the earth that has zero potential. Thus, protects the system and equipment from injury.
 Neutral earthing- In neutral earthing, the neutral of the system is directly connected to earth by the assistance of the GI wire. The neutral earthing is additionally known as the system earthing. Such sort of earthing is generally provided to the system that has star winding. For instance, the neutral earthing is provided within the generator, electrical device, motor, etc.
Equipment earthing- Such sort of earthing is provided to the electrical equipment. The non-current carrying a part of the instrumentation like their gilded frame is connected to the earth with the help of the conductor. If any fault happens within the equipment, the short-circuit current will pass the earth with the assistance of wire. Thus, shield the system from injury.
When we touch a charged body, it loses its charge, because of the method of earthing. Our body may be a smart conductor of electricity and hence it transfers the charges to the earth.

Notes: Importance of earthing- The earthing is crucial thanks to the subsequent reasons.
The earthing provides the simplest path to the flow of short circuit current even when the failure of the insulation. The earthing protects the equipment and personnel from the high voltage surges and lightning discharge. Earthing is done by electrically connecting the various elements within the installation to some system of electrical conductors or electrodes placed close to the soil or below the bottom level. The earthing mat or electrode below the bottom level has a flat iron riser through which all the non-current-carrying gilded elements of the equipment are connected.
