==Key Stage 5==
===Meaning===
A [[dielectric]] is a [[material]] that increases the capacity of a [[Parallel Plate Capacitor|parallel-plate capacitor]] to store [[Electrical Charge|charge]] when placed between the plates.

===About Dielectrics===
*'''Dielectrics''' increase the [[capacitance]] of a [[capacitor]] by reducing the [[Electric Field|electric field]] between the plates.
*Common '''dielectrics''' include polythene, waxed paper, and ceramics.
*The ability of a [[dielectric]] to increase [[capacitance]] is [[measure]]d by its [[Relative Permittivity|relative permittivity]] or [[Dielectric Constant|dielectric constant]].
*'''Dielectrics''' are used to prevent [[Electrical Breakdown|electrical breakdown]] and improve [[Capacitor Energy|energy storage in capacitors]].
*'''Dielectrics''' also influence the [[Electric Field|electric field]] distribution and [[Capacitor Energy|energy storage in the capacitor]].
===Examples===

*Polythene used as a '''dielectric''' in high-[[Potential Difference|voltage]] [[capacitor]]s.
*Ceramic dielectrics in multilayer ceramic [[capacitor]]s (MLCCs) for electronic circuits.
