5. A hollow cylindrical resistor with inner radius ri and outer radius r2, and length 1, is made of a material whose resistivity is p. A) Show that the resistance is given by R = . In "2 for current 2πι r1 that flows radially outward. Hint: Divide the resistor into concenteric cylindrical shells and integrate.] b) Evaluate the resistance R for such a resistor made of carbon whose inner and outer radii are 1.0 mm and 1.8 mm and whose length is 2.4 cm. ( Choose p = 15 x10-5 sm). C) What is the resistance in part (b) for current flowing parallel to the axis?
