Homework Statement I'd like to know how to convert Maxwell's Equations from Differencial form to Integral form. Homework Equations Gauss' Law Gauss' Law for Magnetism Faraday's Law The Ampere-Maxwell Law The Attempt at a Solution Convert using properties of vector analysis (as Divergence and...

I do believe it is a quadratic, based on this calculation. So, does that mean problem is physically impossible if R3 is 20 ohms? Thanks for the huge help btw

Homework Statement [/B] 2. Homework Equations Req= R1 + R2...Rn for resistors in series. Req= (1/R1 + 1/R2 +... 1/Rn)^(-1) for resistors in paralel And Ohm's Rules for circuits The Attempt at a Solution I did manage to solve it by using R3= 0 and thus finding R1= 2000 by using Ohm's Rules...

Thank you for your help.

But why can you assume it spreads symmetrically? Sorry for the late response.

Hi Gneill! Why is the current density assumed to be constant at a radial distance? I didn't understand why that can be done. I know it is related to the hemispheric symmetry...

The answer for this question in the solution manual of Fundamentals of Physics (Halliday) is different, the current across the swimmer is 5.22x10^-2 A. I just didn't understand why the current is constant in a given distance r.
