The dielectric of a parallel plate capacitor is to be a slab of glass that totally fills the volume between the plates. The area of each plate is 0.50 m2.
Find how much more energy is stored in this capacitor compared to an identical one without the dielectric insert?
Find the charge on the capacitor if it is connected to a 12 Volt battery?
Find what thickness should the glass have if the capacitance is to be 0.10 µF?
