What impact does the condition of skin (wet, dry) have on electrical resistance?

The correct choice indicates that wet skin decreases resistance, which is fundamental in understanding electrical safety. When the skin is wet, the moisture facilitates the flow of electrical current through the body. This reduced resistance can lead to a higher risk of serious electrical shock if a person comes into contact with a live electrical current.

In contrast, dry skin has a greater electrical resistance, making it harder for current to pass through. This provides a level of protection against electrical shocks. Therefore, being aware of the state of the skin—whether it’s wet or dry—is crucial when considering safety around electrical sources. Recognizing that wet conditions lower resistance and increase susceptibility to electric shock can help individuals take appropriate precautions to minimize risks.
