PART II: (10 Marks) Problem II-B.1 Determine the effective resistance of a semi-horse shoe structure between its end-to-end faces (A and B) as illustrated in Fig. II-B.1 Note the three metallic parts shown have different resistivity values as indicated. The inner radius of the semi-circular part is a' cm; the length of the vertical post is L cm and the cross-section of the assembly has a width, w cm and thickness, h cm. Derive the necessary formula used 2 ohm/meter ohm-meter ohm-meter FIG. II-B.I Solution hints: suppose 1, 2, 3 are the conducting regions respectively with ρ, p2 and ρ2 resistivities indicated.; and, Ri, R2 and Rj are the corresponding resistance values. Sample answer: Rtotal -R3 (RR2) ohms
