A.Find the resistance for current that flows radially outward. Divide the resistor into concentric cylindrical shells and integrate. Express your answer in terms of the variables r1,r2, l,rho, and appropriate constants.

B.Evaluate the resistance R for such a resistor made of carbon whose inner and outer radii are 1.0mm and 3.0mm and whose length is 4.5cm. rho=15*10^-5 omega*m

C.What is the resistance in part B for current flowing parallel to the axis?
