Grounded

Definition

Grounded means that an object is connected to the Earth, allowing it to transfer or absorb electrical charge. This process helps maintain a stable reference potential and prevents the buildup of excess charge.

5 Must Know Facts For Your Next Test

1. Grounding ensures that the potential of a conductor is zero compared to the Earth.
2. A grounded object cannot retain a net electric charge; it either gains or loses electrons to neutralize its charge.
3. Grounding is used as a safety measure in electrical systems to prevent electric shock.
4. In electrostatic experiments, grounding is often necessary to reset conditions between trials.
5. The Earth can be considered an infinite reservoir of charge due to its vast size.
