Jordvärdet
Jordvärdet, often translated as earth value or ground value, is a concept used in electrical engineering to describe the electrical potential of the earth. In most contexts, the earth's surface is considered to be at zero potential. This is a convention that simplifies electrical circuit analysis, particularly when dealing with grounding systems.
The earth is a large conductor, and its vastness means that it can absorb or supply electrical
The actual potential of the earth can vary under certain conditions, such as during thunderstorms or in
