What is the purpose of grounding in electrical systems?

The purpose of grounding in electrical systems is to create a connection that completes the circuit and carries the current safely away to the ground. Grounding provides a safe path for electric current to follow in case of a fault or short circuit. This safety mechanism helps protect both people and equipment from electric shock and damage. If there is an overload or malfunction, the grounding system directs the excess electricity away from users and sensitive devices, significantly reducing the risk of hazards like fires or electrocutions.

The grounding system also stabilizes voltage levels within the electrical circuit, ensuring that devices can operate safely and effectively without interference or fluctuations in electrical current. This function is crucial for maintaining the integrity of electrical systems in residential and commercial settings.
