Dielectric constant
توضیح فارسی
ضریب ثابت دی الکتریک که با حرف k نشان داده میشود ، نسبت ظرفیت خازنی که عایق آن جسمی به جز هوا است به خازنی که عايقش خلاء باشد.
Description
A number used to indicate the ease with which a particular dielectric material concentrates lines of electrostatic force. A vacuum is used as the reference and is assigned a dielectric constant of one. The dielectric constant of air is very near that of a vacuum; it is 1.0006. Mica allows the lines of electrostatic force to pass much more easily, and it has a dielectric constant of 7. The dielectric constant of the insulating material in a capacitor determines its capacity.
