Dielectrics are insulating materials that contain polar molecules. This dielectric material reduces the electric field between the plates of a capacitor and improves its capacitance. If the original capacitance of a capacitor with only a vacuum (or air) between the plates was Co, then the capacitance with the dielectric between the plates is C = K· Co Two 6.03 cm diameter metal disks are separated by a 0.231 mm thick piece of paper. The dielectric constant for paper is Kpaper = 3.7 and its dielectric strength is 16 x 10® V/m.
