How does dry skin affect electric current?

Dry skin primarily has high resistance to electric current, which makes it less conductive compared to other materials. When skin is dry, the moisture content is low, causing the skin to act almost like an insulator rather than a conductor. This high resistance means that it is more difficult for electricity to pass through the skin, reducing the likelihood of a shock occurring compared to when skin is moist or wet.

In contrast, moist or wet skin significantly lowers resistance, allowing electric current to flow more easily, which can lead to an increased risk of shock. Therefore, understanding the relationship between skin condition and resistance is vital for electrical safety.
