9. [-/2 Points] DETAILS V Electric current passing through a human body can be dangerous, even fatal, depending on the amount of current, the duration of the current, and the region of the body through which the current passes. However, currents less than about 0.5 mA are typically imperceptible. A current caused by a low potential difference typically travels through the outer layer of the skin. The resistance of the skin therefore determines how much current flows for a given potential difference. The resistance can be influenced by a number of factors, including whether the skin is wet or dry. MY NOTES For example, suppose an electric current of 84.0 µA follows a path through the thumb and index finger. When the skin is dry, the resistance along this path is 3.10 × 105 №. What voltage (in V) is required for this current, in the case of dry skin? When the skin is wet, the resistance is lowered to 1,600 2. What voltage (in V) is required for the same current, in the case of wet skin? PRACTICE ANOTHER Need Help? Read It
