O QUE SIGNIFICA DIELECTRIC EM INGLÊS
Dielétrico
Um material dielétrico é um isolador elétrico que pode ser polarizado por um campo elétrico aplicado. Quando um dielétrico é colocado em um campo elétrico, as cargas elétricas não fluem através do material como fazem em um condutor, mas apenas ligeiramente deslocam-se de suas posições de equilíbrio médias, causando polarização dielétrica. Devido à polarização dielétrica, as cargas positivas são deslocadas em direção ao campo e as cargas negativas se deslocam na direção oposta. Isso cria um campo elétrico interno que reduz o campo geral dentro do próprio dielétrico. Se um dielétrico é composto de moléculas fracamente ligadas, essas moléculas não só se tornam polarizadas, mas também reorientam para que seu eixo de simetria se alinhe ao campo. O estudo das propriedades dielétricas diz respeito ao armazenamento e dissipação de energia elétrica e magnética em materiais. Os dielétricos são importantes para explicar vários fenômenos em eletrônica, óptica e física de estado sólido.
definição de dielectric no dicionário inglês
A primeira definição de dielétrico no dicionário é uma substância ou meio que pode sustentar um campo elétrico estático dentro dele. Outra definição de dielétrico é uma substância ou corpo de condutividade elétrica muito baixa; isolador. O dielétrico também é, preocupado ou com propriedades de um dielétrico.

CITAÇÕES EM INGLÊS COM «DIELECTRIC»
Citações e frases célebres com a palavra
dielectric.
Elementary considerations led me to the conclusion that a medium, composed of layers of different dielectric constants, must behave as a uniaxial crystal if it is assumed that the layer thicknesses are only a fraction of a wave-length.
