1. The problem statement, all variables and given/known data Consider two small conductive spheres in radius a and b located far from each other. In t=0 "a" sphere charged with Q and "b" sphere neutral. We connect the spheres by wire with resistance R. Find the charge on each sphere as a function of time. 2. Relevant equations d[tex]\rho[/tex]/dt+divJ=0 I=dQ/dt J=[tex]\sigma[/tex]E R=[tex]\rho[/tex]*(L/A) 3. The attempt at a solution I'm assumed that the change in charge in one sphere is the same in the other sphere with opposite sign. I tried to understand what is the relevant electric field and where should I calculate it (outside the sphere? Inside the wire?). I think that capacitance Required here but the two spheres connected so it more like capacitor discharge… I'm lost.
