3. You have likely been warned to avoid contact with electrical appliances or even electrical outlets when your hands are wet. Such contact is more dangerous when your hands are wet (vs. dry) because wet hands cause .

your resistance to be lower

Explanation:

water is good conductor of electricity so when the hands are wet they have relatively less resistance compared to dry hands.
