What factor makes moist or wet skin more dangerous in terms of electrical shock risk?

Explanation:
Moist or wet skin lowers the body's electrical resistance, so more current can pass through the body at the same voltage. The danger from electrical shock comes from the amount of current that can flow, and water with salts makes the skin a much better conductor, drastically reducing impedance. With lower resistance, the same voltage drives a larger current, increasing the risk of harm, especially along paths that involve the heart. Dry skin has higher resistance and limits current, while an insulating layer would block current more effectively. So, the key factor is that wet skin acts as a better conductor, allowing more current to pass.
