Neglect the end surfaces of the cylinder and assume that the thickness is much smaller than the radius.

Cheap resistors are fabricated by depositing a thin layer of carbon onto a non-conducting cylindrical substrate (see Figure P2.44). If such a cylinder has radius a and length d, determine the thickness of the film required for a resistance R if:
