If earth electrode resistance is very high, what consequence is likely?

Explanation:
The main idea here is that the grounding system must provide a low-impedance path for fault currents. When earth electrode resistance is very high, the path to earth is weak, so fault current is significantly limited. Protective devices rely on a certain current level to trip quickly. If the fault current is too small, the protective device may take longer to operate or may not trip promptly at all, leaving the fault active longer. That delay increases the risk of electric shock, insulation damage, arcing, and fire. So, high earth resistance leads to poor grounding and slower fault clearance, which is unsafe.
