Dielectric is something analogous to current flow over a capacitor arrangement at the time of  the charging process when current introduced at one plate (usually a metal) flows through the insulator to charge another plate (usually a metal). Dielectric materials have been used in numerous applications encompassing coatings on conductorse.g., cables, wires! Passive devices in circuits e.g., capacitors! Insulators in active devices e.g., gate dielectrics in transistors. Ceramic components are used in packages for semiconductor integrated circuits, as well as in automobile engines, in composites for aerospace vehicles, and in high efficiency power generation stations. Dielectrics play important roles in applications ranging from sensors, isolation for conductors in the power utility industry, to ceramic cookware. Further, in the promptly emerging area of biological systems, the dielectric constant is important because electrostatic effects are used to link structure and function of biological molecules. Dielectric materials such as ferroelectric and piezoelectric nanomaterial’s offer significant advantages for communication devices and data storage systems.
