Grounding is a fundamental safety measure in electrical systems that serves to minimize the voltage difference between an object and the Earth. When an object is grounded, it is connected to the Earth, which acts as a reference point for voltage. This connection helps ensure that in the event of a fault or short circuit, any excess electricity is safely directed into the ground, thereby reducing the risk of electric shock and equipment damage.

By establishing a direct electrical connection with the Earth, grounding helps equalize potential differences that might exist between an object and the surrounding environment. This can prevent the buildup of static electricity, minimize the risk of fires, and ensure that protective devices, like circuit breakers, function correctly. Overall, grounding creates a safer electrical environment by maintaining the object at a similar potential as the Earth.
