Biomedical Application. The parts of the body that are most sensitive to electric currents are brain. The chest, muscles and the nerve centers that controls respiration and the heart. A current of 1 mA passing through the body will barely be noticeable, but a current of 80 mA will usually be fatal unless it is immediately stopped. In most situations, the amount of current that will flow into the body will depend on the condition of the skin at contact locations. Dry skin will have a high resistance but damp or wet skin will have a low resistance. Why?

An electric eel generates electric currents through its highly specialized Hunter's organ, in which thousands of disk-shaped cells called electrocytes are lined up in series, very much in the same way batteries are lined up inside a flashlight. When activated, each electrocyte can maintain a potential difference of about 150 mV at a current of 1 A for about 2.0 ms. Suppose a grown electric eel has 3.50 ✕ 103 electrocytes and can deliver up to 300 shocks in rapid...

Magnetism is produced by circulating electric currents, but also by the spin of elementary particles and many atoms that are small magnets. An electric current I circulating in a wire of radius R, produces a magnetic field in the center of the wire of value B = u or I /) 2r). (uo - 1.26 x 10 ^ -6 T m / A). We can use this formula as a model for three situations: the Earth, an atom of iron...

8. What are the species in the event that the ratio of brain weight to body weight is greater than 0.02? Remember that brain weight is recorded in grams and body weight in kilograms, so body weight must be multiplied by 1000 to make the two weights comparable. The species belonging to this event can be obtained with the R command > subset(mammals,brain/body/1000 > 0.02) What is the probability of that event?
