Question

Need help with the last part please

Dog Updated We're going to estimate the end-to-end (nose-to-tail) resistance of Dr. Kuo's puggle. This will have to be a coarse estimate if we want to avoid calculus. Let's treat the dog as a cylinder of skin with some thickness, filled with innards of nearly zero resistance As seen in the picture, we can separate the cylinder into two endcaps and a long center portion. The center portion has a cylindrical portion of innards surrounded by a cylindrical shell of skin. Let each piece have a diameter of D 20 cm, let the center portion have a length of L60cm, and let each section of skin have a thickness of t1 cm. Dog skin under typical conditions has a resistivity of p 3.2M2-m. There are four components here (the two endcaps, and the two center portions) Which of the circuit diagrams below best represents their arrangement? Assume that we're going to show the nnards on the diagram, even if their resistance is negligible. Let A and D indicate the endcaps, B indicate the cylindrical shell of skin, and C the innards DiagramI -WDiagram II Diagram IVD Correct: Diagram I. Incorrect Diagram II Incorrect Diagram III.
