The high resistivity of the soil impede the flow of current and the large voltage develops across the earth electrode and soil. This will result into higher voltage ( step or touch potential) on the grounding system. The higher voltage developed in the grounding system due to higher soil resistance may cause electric shock to person working near the earth pit.
