A ground rod that penetrates perpetually moist earth will have what kind of resistance?

A ground rod that penetrates perpetually moist earth will have low resistance because moisture enhances the conductivity of the surrounding soil. Water is a good conductor of electricity, and when a ground rod is buried in consistently moist soil, it allows for more efficient dissipation of electrical energy into the ground. This improved conductivity lowers the resistance between the ground rod and the earth. The presence of minerals and dissolved ions in moisture further contributes to reducing resistance, making it an effective pathway for grounding purposes.
