Grounding

Definition

Grounding is the process of connecting an electrical circuit to a reference point, typically the Earth, to ensure safety and stability. It allows excess charge to dissipate safely into the ground.

5 Must Know Facts For Your Next Test

1. Grounding provides a common reference point for voltage levels within a circuit.
2. It enhances safety by preventing the buildup of static electricity that could cause electric shocks or fires.
3. In circuits with grounding, the potential difference between grounded components is zero.
4. Equipotential lines in a grounded system will always be at zero volts relative to the ground.
5. Grounding is essential for protecting sensitive electronic equipment from voltage spikes.
