having dry hands - electricity

Touching an electrical appliance with wet hands is dangerous!
Water can conduct electricity.
Also, the resistance of our skin varies from person to person and fluctuates between different times of day. In general, dry skin is a poor conductor that may have a resistance of around 100,000 Ω, while broken or wet skin may have a resistance of around 1,000 Ω.
Tah-Dahs!
