- 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 . For example, suppose an electric current of 89.0 µA follows a path through the thumb and index finger. When the skin is dry, the resistance along this path is 4.40 ✕ 105 Ω. What voltage (in V) is required for this current, in the case of dry skin? V When the skin is wet, the resistance is lowered to 1,950 Ω. What voltage (in V) is required for the same current, in the case of wet skin? Varrow_forwardConsider a portion of a cell membrane that has a thickness of 7.50 nm and 1.8 pm x 1.8 um in area.

The human body is a complex and beautiful marvel of Evolution. It is also a bag of salty water with resistivity 5Ω⋅m . Let's get a sense for the inherent danger of different voltages applied across the body. From left hand to right hand, we approximate the body / torso as a tube 1.6 m long, 10 cm in diameter. We will consider two skin conditions -- wet skin (e.g. with salt water on it) in which case the skin's resistance is negligible, and dry skin which has much higher resistance. 1. First, if the skin is wet, what is the resistance from left hand to right hand (in ohms, to 3 significant digits)? 2. If the resistance from right hand to left is 500kΩ when skin is dry, what is the resistance of a single layer of dry skin (answer in kΩ , with 2 significant digits)? 3. A current of 100 mA passing from right hand to left can easily be lethal. If your hands are dry, what voltage is lethal (2 significant digits)? 4. A current of 100 mA passing…arrow_forward
