When inspecting electrical systems, what does a lower resistance reading generally indicate?

A lower resistance reading during the inspection of electrical systems typically indicates better grounding. Good grounding is crucial for the safety and proper functioning of electrical systems, as it provides a low-resistance path for electrical current to flow into the earth in case of faults. This minimizes the risk of electric shock, reduces electromagnetic interference, and helps protect equipment from damage due to electrical surges or faults.

When the resistance is low, it suggests effective grounding connections, which are capable of safely dissipating excess current. In contrast, higher resistance could imply poor grounding, which may not adequately protect the system or individuals from electrical hazards. This context reinforces why a lower resistance reading is desirable in assessing grounding quality in electrical systems.
