What effect does high humidity have on electrical safety?

• A. It enhances insulation
• B. It decreases resistance
• C. It has no effect
• D. It always improves safety

Answer: (B)

High humidity decreases resistance in the context of electrical safety. When humidity levels are high, the moisture in the air can create a more conductive environment. This increase in conductivity means that electrical current can flow more easily, potentially leading to short circuits and other electrical hazards. In environments with high humidity, moisture can accumulate on surfaces and in materials that are meant to be insulating. This moisture can bridge the gap between conductive elements, effectively lowering the resistance and increasing the chances of electrical accidents, such as shocks or fires. Thus, understanding the implications of high humidity on resistance is crucial for maintaining a safe workplace regarding electrical safety.
