Answer: A good ground resistance value is typically below 5 ohms. However, specific standards or applications may have different acceptable ranges. Lower resistance values ensure efficient grounding and electrical safety. Reasoning: Efficient Grounding: Low ground resistance allows efficient dissipation of electrical currents into the ground, minimizing the risk of electric …

Why Salt and charcoal are added to the earthing pit? Answer: Salt and charcoal are added to the earthing pit to enhance soil conductivity. Salt improves water retention in the soil, ensuring a consistent moisture level, while charcoal aids in preventing corrosion and maintaining low resistance for effective grounding. Reasoning: …
