The electrical resistance in your body decreases when you get wet because water can act as a conductor of electricity. When you are dry, the outer layer of your skin acts as an insulator, meaning it restricts the flow of electrical current. However, when you get wet, the water on your skin contains dissolved salts and minerals, which make it into a conductive medium. This results in the reduction of resistance, as the conductive nature of the water allows electricity to easily flow through your body. The salts in the water, especially sodium and chloride ions, enhance its conductivity, making it easier for electrical signals to pass through your body. This is why it is important to exercise caution around electrical equipment or exposed wires when you are wet, as the decrease in resistance can increase the risk of electric shock.
