Answer 2

To make a GI earth pit with salt and coal, start by digging a pit in the ground. Line the pit with a layer of salt, followed by a layer of coal. Place the GI (Galvanized Iron) rod in the center of the pit and cover it with more salt and coal, alternating layers until the pit is full. This setup can help improve grounding for electrical systems.
