Lightning- current Ed- A Figure above indicates one reason no one should stand under a tree during a lightning storm. If lightning comes down the side of the tree, a portion can jump over to the person, especially if the current on the tree reaches a dry region on the bark and thereafter must travel through air to reach the ground. In the figure, part of the lightning jumps through distance d in air and then travels through the person (who has negligible resistance relative to that of air because of the highly conducting salty fluids within the body). The rest of the current travels through air alongside the tree, for a distance h. If d/h = 0.49 and the total current is I =0 1637 A, what is the current I, = A through the person?

15 A defibrillator passes a brief burst of current through the heart to restore normal beating. In one such defibrillator, a 42.7-μF capacitor is charged to 5.90 kV. Paddles are used to make an electric connection to the patient’s chest. A pulse of current lasting 1.00 ms partially discharges the capacitor through the patient. The electrical resistance of the patient (from paddle to paddle) is 240 Ω. How much energy is dissipated in the patient during the 1.00 ms? _____J

Which of the following is the correct physical explanation for the dangers posed by large currents passing through the human body? Question 14 options: The energy delivered during electrocution is proportional to the amount of current. The number of protons passing through the body from electrocution is dangerous. The resistive heating that occurs from electrocution is proportional to the amount of current. The large current absorbs a lot of heat from the body as it passes through tissues.
