[QUOTE="YoshiMoshi, post: 5227008, member: 541098"] [h2]Homework Statement [/h2] Please see the picture attached. [h2]Homework Equations[/h2][h2]The Attempt at a Solution[/h2] I was able to solve part A correctly, at least I believe I was able to do so. I'm struggling with part (b) however. I'm not sure were to start on this. My test that has this problem doesn't have anything on MLT. I pulled out my Power Electronics book from my undergraduate and found that R = (rho * l_b)/A_w R -> Resistance of the winding rho -> resistivity of the conductor material l_b is the length of the wire A_w is the wire bare area I believe I need to find l_b? I don't understand exactly how I can go about this. I believe that for A_w A_w = (5 cm)(3 cm) = 15 cm^2 I used 3 cm because it's a 3 cm stack as specified in the problem Am I just supposed to assume for rho that I'm using copper winding? I don't understand the hint and how I'm supposed to solve the problem using Ohm's law. The wire has a resistance R, and I found the MMF in part A, but not the voltage. Hence I'm stuck because V = IR I don't know V or I. and I know that F = IN Where I solved for F in part (a) but don't know I or N Any help would be greatly appreciated. [/QUOTE]
