1. The problem statement, all variables and given/known data
thin wire connecting two conductors, a big sphere and a small sphere. What sphere has the most charge?
2. Relevant equations
3. The attempt at a solution
The charge will want to distribute itself over the entire surface area of the two conductors. Therefore because of the larger sphere having more surface area, there will be more charge on the larger sphere. IS this a logical way of approaching this problem?

If both spheres had a a previous charge and then were connected with the wire, both will now have the same potential put different charges, although the total charge wont change:
V1= k*Q1/R1 V2=k*Q2/R2
Now V'1=V'2 so: Q1'=V'*R1/K Q2'=V'*R2/K
and Q1 + Q2 = Q1' + Q2'

That makes sense! I think I was on the right track. Thanks!
