What three factors greatly affect skin resistance?

Explanation:
Skin resistance varies with how the current can path through the skin. A larger contact area creates more parallel paths for current, lowering the overall resistance. Moisture in the skin adds ions and water content that greatly increases conductivity, reducing resistance even further. The voltage applied across the skin also matters: higher voltage can overcome the skin’s insulating properties, causing breakdown and a drop in effective resistance. Because current depends on voltage and resistance, these three factors together determine how easily current can pass through the skin.
