What is grounding definition?

Grounding, in electrical engineering, is a safety measure used to prevent electric shock and damage to electrical appliances. Grounding involves connecting an electrical device or appliance (such as a surge protector or outlet) to a wire that is physically connected to the earth. This wire serves as a pathway for current to safely flow to the earth in the event of a short circuit or other electrical fault.

Grounding also helps to prevent electrical interference, known as "noise," that can weaken signal strength or cause problems with electronic devices. Grounding is particularly important in settings where there is a risk of electrical shock or where sensitive electronic equipment is used, such as in hospitals, labs, and factories.

Grounding may be achieved through physical grounding (such as using a grounding rod buried in the earth) or through electrical grounding (such as connecting to a grounded electrical outlet). Safety standards and regulations for grounding may vary depending on the industry and the specific application.
