Hi, I would really appreciate clarification on the definition of capacitance in this context: Suppose I have 3 concentric metal spherical shells and they have charges Q1,Q2,Q3 and potentials 0,V,0 and radii a,b,c respectively, what is the capacitance of the configuration?

2. Relevant equations

C=Q/V

3. The attempt at a solution

I know what the capacitance is with only 2 spheres but I am not sure what it means with 3.
