Ground mats are used to extend what aspect of an equipotential zone?

Ground mats serve to enhance the surface area aspect of an equipotential zone. By increasing the surface area in contact with the ground, ground mats effectively distribute electrical potential more evenly across a wider area. This is particularly crucial in situations where there may be a risk of electric shock due to differences in potential between various points on the ground.

By extending the surface area, ground mats help to minimize potential difference within the zone itself, promoting safety for personnel and equipment in electrical environments. The larger area allows for better grounding capabilities, which can also help in dissipating electrical faults more efficiently. Thus, focusing on increasing surface area is essential for establishing a stable and safe equipotential zone.
