GO Swimming during a storm. Figure 26-31 shows a swimmer at distance D = 35.0 m from a lightning strike to the water, with current I = 78 kA. The water has resistivity 30 Ω·m, the width of the swimmer along a radial line from the strike is 0.70 m, and his resistance across that width is 4.00 kΩ Assume that the current spreads through the water over a hemi-sphere centered on the strike point. What is the current through the swimmer?

The power link delivers a maximum power of 600 MW at full capacity with an operating voltage of 500 kV. Solve for the resistivity of the cable, assuming a conductor diameter of 1.5 cm.

The legend that Benjamin Franklin flew a kite as a storm approached is only a legend — he was neither stupid nor suicidal. Suppose a kite string of radius 2.10 mm extends directly upward by 0.802 km and is coated with a 0.520 mm layer of water having resistivity 155 Ω·m. If the potential difference between the two ends of the string is 176 MV, what is the current through the water layer? The danger is not this current but the chance that the string draws a lightning strike, which can have a current as large as 500 000 A (way beyond just being lethal).arrow_forwardThree wires, of the same diameter, are connected in turn between two points maintained at a constant potential difference. Their resistivities and lengths are r and L (wire A), 1.2r and 1.2L (wire B), and 0.9r and L (wire C). Rank the wires according to the rate at which energy is transferred to thermal energy within them, greatest first.arrow_forward

Its stainless-steel shield has an inner diameter of 0.350 mm, and its Nichrome conductor has a diameter of 0.170 mm. Nichrome is used because its resistance does not change much in going from room temperature to near absolute zero. The insulating dielectric is magnesium oxide (MgO), which has a dielectric constant of 9.70. Calculate the capacitance per meter of Thermocoax.arrow_forward
