Why is it easy to get an electric shock when hands are wet? Current = voltage / resistance, so the amount of current passing through the human body depends on the withstand voltage divided by the total resistance of the human body to form a loop. The resistance in the human body is about 100,000 ohms when the skin is dry. At a voltage of 110V and 60Hz, the current is only 1.1 mA, and it has only a tingling sensation. However, when the skin is wet, the resistance will become smaller, and the greater the current flowing through the body, which is why it is particularly easy to get an electric shock after taking a bath or having wet hands.
