Correct option is A
Earthing (or grounding) is crucial in electrical systems for safety and proper operation. It provides a low-resistance path for fault currents, reducing the risk of electric shock, equipment damage, and fire hazards.
· High voltage equipment operates at significantly high potential differences, increasing the risk of electric shock and insulation breakdown.
· Proper earthing ensures that any leakage or fault current is safely discharged into the ground, protecting both humans and equipment.
