The figure 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). The rest of the current travels through air alongside the tree, for a distance h. If d/h = 0.431 and the total current is I = 5270 A, what is the current through the person? Number i Units Lightning- current

Lightning is a spectacular example of electric current in a natural phenomenon. There is much variability to lightning bolts, but a typical event can transfer 10^9 J of energy across a potential difference of perhaps 5 x 10^7 V during a time interval of about 0.2 s. Use this information to estimate (a) the total amount of charge transferred between cloud and ground (b) the current in the lightning bolt (c) the average power delivered over the 0.2 s.
Lightning strikes can involve currents as high as 25,000 A that last for about 40 ms. If a person is struck by a bolt of lightning with these properties, the current will pass through his body. We shall assume that his mass is 75 kg, that he is wet (after all, he is in a rainstorm) and therefore has a resistance of 1.0 kΩ, and that his body is all water (which is reasonable for a rough, but plausible, approximation). (a) By how many degrees Celsius would this lightning bolt increase the temperature of 75 kg of water? (b) Given that the internal body temperature is about 37oC, would the person’s temperature actually increase that much? Why not? What would happen first?
A person grasps the ends of an electrically conducting copper wire in each hand. The wire has a cross-sectional area of 4.0×106 m² and its surface is not insulated. If the person's hands are wet, the resistance of the possible electrical pathway from one hand, up the arm, across the chest and down into the other hand is about 1 kQ. (a) A current of 10 mA can “freeze" the muscles so the hands are clenched around the wires. Estimate the potential difference between the ends of the wire which would cause this. (b) How much power is dissipated in the person's body if this current flows? (c) The ends of the wire are connected to make a circuit that includes a battery. If the person grasps the wire with hands 0.20 m apart, comment on the resistances of the possible paths of electric current. The resistivity of copper is 1.7x108 Qm.
Two wires of circular cross section are made of the same metal.Wire 1 has radius r and length L; wire 2 has radius 2r and length 2L. Thepotential difference between the ends of the wire is the same for both wires.For each of the following quantities, find the ratio of its value for wire 2to its value for wire 1: current in the wire
Electric Eels. Electric eels generate electric pulses along their skin that can be used to stun an enemy when they come into contact with it. Tests have shown that these pulses can be up to 500 V and produce currents of 80 mA (or even larger). A typical pulse lasts for 10 ms. What power and how much energy are delivered to the unfortunate enemy with a single pulse, assuming a steady current?
Consider a resistor made of copper that you connect to a 12.0 V power supply in an oven where the temperature is 300°C. In this heat, you find that a current of 2.00 A goes through the resistor. Determine the current that goes through this resistor if you connect it to the same power supply but this time on the surface of Mars where the temperature is about -100°C.

Construct Your Own Problem. Consider a battery used to supply energy to a cellular phone. Construct a problem in which you determine the energy that must be supplied by the battery, and then calculate the amount of charge it must be able to move in order to supply this energy. Among the things to be considered are the energy needs and battery voltage. You may need to look ahead to interpret manufacturer’s battery ratings in ampere-hours as energy in joules.
Biomedical Application. The parts of the body that are most sensitive to electric currents are the brain, the chest muscles and the nerve centers that controls respiration and the heart. A current of 1mA passing through the body will barely be noticeable, but a current of 80mA 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 low resistance. Why?

A high-voltage dc power line falls on a car, so the entire metal body of the car is at a potential of 10,000 V with respect to the ground. What happens to the occupants (a) when they are sitting in the car and (b) when they step out of the car? Explain your reasoning.
