SOLVED: Consider a parallel-plate capacitor that is partially filled with a dielectric of dielectric constant K. The dielectric has the same height as the separation of the plates of the capacitor but fills a fraction f of the area of the capacitor. The capacitance of the capacitor when the dielectric is completely removed is C0. What is the capacitance C(f) of this capacitor as a function of f? Express C(f) in terms of C0, f, and K.

SOLVED:A vertical parallel-plate capacitor is half filled with a dielectric for which the dielectric constant is 2.00 (Fig. P26.71a). When this capacitor is positioned horizontally, what fraction of it should be filled with the same diclectric (Fig. P26.71b) so that the two capacitors have equal capacitance?
