So I need to study Lenz's law and have only learned the absolute basics so far. I'm a little stuck on this study question. I'd really appreciate anyone who helps solidify my understanding of it a little bit! Homework Statement Consider a circular loop of wire near a long...

Thanks a bunch for the help, gneill and praharmitra!

Alrighty. So part (1) of the question is complete. (2): Looking at the re-drawn circuit, the net resistance between A and B (given that each resistor has the same resistance R) should be: 1 / (8 x (1/R)) which is equal to R / 8 (3): There is no resistance between B and C. That path bypasses...

Good point. I say zero because for any two given points on that octagon, there always exists a path that need not go through any resistors. Edit: I just saw your addition to my diagram (thank you!) and my guess appears to be correct.

Egads! I see that. However, I don't think I understand what implications that would have when, for example, measuring the resistance between points A and B, and B and C. Does the redrawn circuit just look like this? [PLAIN]http://img844.imageshack.us/img844/4661/phystopic2.gif If this...

Each end of the two resistors shares the same connection, causing each to have the same potential difference, right? Isn't it just zero?

(Solved) Calcuating the resistance of a circuit. Hey everyone, long time lurker, first time poster. Glad to be here! I have a few physics problems that I need assistance with. I may create another thread later. For now, here's this: Homework Statement Consider the following circuit...
