Problem
A parallel-plate capacitor has fixed plate separation and is filled with a dielectric of constant κ. Which single change listed below will most directly double its capacitance?
(a) Double the potential difference applied to the capacitor while keeping its geometry and dielectric constant unchanged.
(b) Increase the plate area to twice its original value while keeping all other factors the same.
(c) Double the plate separation while keeping the plate area and dielectric constant unchanged.
(d) Reduce the dielectric constant to half its original value while keeping the geometry unchanged.
