誘電体

誘電体

dielectric material

[目次:結晶等(結晶構造/材料試料)]

絶縁体と同義語。自由電子がなく、全ての電子が原子や分子によって束縛されている物質。これに電場をかけると、自由電子がないので電流は流れないが、誘電分極により誘電体の表と裏の面に正負の電荷が発生し、電気的エネルギーが蓄えられる。

"Dielectric material" is equivalent to "insulator." In a dielectric material, no free electrons exist or all electrons are bound to atoms or molecules. When an electric field is applied to a dielectric material, no electric current flows because of no free electrons in the material, but positive and negative charges are created on one surface and the other surface due to dielectric polarization, electric energy being stored.
