At the bottom of page 482 there is something called “got it? 27.7”. It discusses a wire loop with three resistors symmetrically placed around the loop. The loop has an induced current, associated with a changing magnetic field; they ask about voltage differences in this system, particularly the readings of volt meters which they describe.
Has anyone looked at this? I think it's an interesting question. I am not sure that I agree with what the book says about this. Please feel free to comment here and engage in an open discussion of this potentially interesting topic. What do you think?
Is it the set up that you don't agree with? The circuit, the way they have it, is not experiencing the change in magnetic field; the magnetic field in one "loop-slice" is pretty uniform so there is no induced electric field and therefore no induced emf to read with the voltmeter? Or does this not matter?
ReplyDeleteI am not sure. I have been working on this problem for about an hour, coming up with different conclusions that were later discredited by further reading...
I am curious to know what the conundrum is!
