Homework Statement
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.
Homework Equations
d[tex]\rho[/tex]/dt+divJ=0
I=dQ/dt
J=[tex]\sigma[/tex]E
R=[tex]\rho[/tex]*(L/A)
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.
