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

Our body is an electrical conductor. If we touch a charged body with our hand, the charges are conducted through our bodies to the earth.

When electric charges are transferred to earth directly with minimum resistance, an instantaneous discharge of the charged body occurs.
This phenomenon is called earthing.
Therefore, if we touch it with our hand, the charged body loses its charge due to earthing.
