What is earthing resistance: Meaning, Formula, Calculation & Practical Guide
What Is Earthing Resistance? Earthing resistance is the opposition offered by an electrode while dissipating current into the ground. Its main formula is: R = ρ / 2πL (ln(4L/d) – 1). The ideal value for homes is 1–5 Ω, and for industries, it is less than 1 Ω̣. Introduction Earthing resistance is one of the … Read more
