Q: Dielectric materials get charged instantaneously under the influence of an electric field. Is it true or false?  

Dielectric materials exhibit the property of instantaneous charging when subjected to an electric field. This property arises from their ability to store electric energy easily due to their relatively higher permittivity compared to other materials. When an electric field is applied, the electric dipoles in the dielectric material align themselves with the field, resulting in the accumulation of positive and negative charges on opposite ends of the dipoles. This process occurs instantaneously, allowing the dielectric to store electrical energy efficiently. It is this ability to store charge that makes dielectric materials indispensable in various applications, such as capacitors.
