We wish to determine the resistance across the diameter of the cylinder t Status re for view Otheexpertta.com 50% Part (a) Integrate over the diameter of the cylinder to write an equation for the resistance in terms ofp, H and r Status Partial Completed Final Grade Student Answer R (p)( 2 H ) Feedback Correct Answer 100% Grade Detail Partial Correct Student Final Answer Credit 100% Submission History Answer Completed Hints Feedback Totals 09.0 0% 090 | 0% Totals 0% 090 0% | 0% 50% Part(b) Calculate the resistance for the cylinder, in units of m2.Explanation / Answer
A)R = pi rho/(2 H) - Correct
B)R = pi rho/2 H
R = 3.14 x 4.3 x 10^-5/(2 x 0.035) = 1.93 x 10^-3 Ohm
Hence, R = 1.93 milli-Ohm
