In your new job at an engineering company, your supervisor asks you to fabricate a resistor that has a resistance of R = 0.190 and no change in resistance with temperature. She suggests making the resistor from lengths of cylindrical carbon and Nichrome wires of equal radius, placed end-to- end. She wants the combination to fit into a machine that allows for a radius of the resistor to be r = 1.13 mm. What are the lengths of the two segments of the resistor (in m)? Nichrome 0.000105 X Write an equation for the total resistance and then impose the fact that the changes in resistance due to temperature must have the same magnitude. m carbon 0.000105 X Write an equation for the total resistance and then impose the fact that the changes in resistance due to temperature must have the same magnitude. m

A nichrome rod of length LN = 78 cm is connected in series (end to end) to a carbon rod of length LC = 5 cm. Both rods have cross-sectional areas of A = 85 mm2. At T0 = 20° C the restistivity of nichrome is ρN = 1.50 × 10-6 Ω⋅m and the resistivity of carbon is ρC = 3.50 × 10-5 Ω⋅m. The temperature coefficient of nichrome is positive with value αN = 0.4 × 10-3 °C-1. The temperature coefficient of carbon is negative with a value αC = -0.5 × 10-3 °C-1.

Kiting during a storm. 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).
A material is inserted between a pair of concentric metallic cylinders of radii a and b where b > a as shown in the figure. The length of the cylinders is e and t >> b. Potential difference is applied between the inner and the outer surfaces, which results in an outward current in the radial direction. Resistivity of the material is given by p = por where py is a constant and r is the cylindrical radial coordinate. What is the resistance of the material?
