This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

  • Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
  • Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
  • Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
  • Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

This looks like a fascinating, though very non-trivial, type of problem. I will send a link to a finite element analysis program which solves this kind of scenario. I recommend looking at video #1 (thin film resistance). There is an option to make it full-screen. This is just to illustrate the complexity of this type of problem.

Sir is it difficult to calculate resistance of this plate ?? Is it difficult to take small elements for integration?

@Kudo Shinichi The lines of equal current might form curved loops, like the ones shown in the video. I think you would have to use something like variational calculus to derive the current distribution, or use a finite element simulation. Do you know what the answer is supposed to be?

@Steven Chase By dimensional analysis and some calculations we would get it to be Ia/sigmabt , I think real answer should be of this form with some constant sir

@Kudo Shinichi Sir can the answer be in this form with some constant multiplying ?
