B8: Capacitors, Dielectrics, and Energy in Capacitors
The simplest kind of capacitor is the parallel-plate capacitor. It consists of two identical sheets of conducting material (called plates), arranged such that the two sheets are parallel to each other. In the simplest version of the parallel-plate capacitor, the two plates are separated by vacuum. The capacitance of such a capacitor is given by

Assuming, as seems reasonable, that these plates carry zero charges when zero potential difference is applied across the two capacitors, it follows that in the presence of a non-zero potential difference the charge +Q on the positive plate of capacitor 2 must be
Parallel Plate Capacitor
Yes, the capacitance of a parallel plate capacitor can be adjusted by changing the distance between the plates, the area of the plates, or the type of dielectric material used. For instance, bringing the plates closer together, increasing the plate area, or using a dielectric material with a higher dielectric constant will increase the capacitance.
