Yeah, I solved the cylindrical one (ii) correctly, I just just plugging values in incorrectly. The spherical one is still giving me issues though, I'm getting a = b + (C / (4 * Pi * E)), which means that a will always be greater than b, an impossible situation when a is the inner radius. So I...

whoops, i had them labeled wrong. (i) is the capacitance of a spherical capacitor, and (ii) is the capacitance of a cylindrical capacitor. h is the height of the capacitor. Hm, I must be entering values into my calculator incorrectly... rechecking now.

The equations are solved for a correctly? There is no h in the spherical formula.

Homework Statement I have two homework problems, both of which require me to solve the equation for the capacitance of a capacitor for the inner radius of the capacitor (one cylindrical, one spherical). This shouldn't be a problem, but I think my algebra is screwy. a = inner radius b = outer...
