Ok so my question(s) has more than one part.
First, the energy stored in capacitor is ##(1/2)CV^{2}## , is the ##V## the voltage of the source that charged the capacitor?? If I had two identical capacitors, and charged one using a 9V source and one using a 12V source, would the one charged by a 12V source have more energy?
Second, what would be a material with a high dielectric constant, and how much would it cost by the kilo? I've been looking around and have found materials like Lead Magnesium Niobate, which has a high dielectric constant, but I can't find prices for these materials.
Thanks for any help!
