The following figure shows a cylindrical shell of internal radius a, external radius b and height h. h a) Suppose there is a potential difference between the inside of the cylinder and the outside. external part. Calculate the electrical resistance for the case where the resistivity is constant: p = po, with po being a positive constant. b) Repeat the previous point, if now the resistivity varies radially according to the relation p=pire“Br, with p1 and ß positive constants. 1 c) With the result of part a) determine the material of which the cylinder is made if it has a resistance of 1.8 u12. Consider that: a = 2 cm, b = 20 cm, h = 10 cm. d) If the potential difference between a and b were 1 mv. What would be the current would flow? Use the data from part c).
