Question

how is dielectric constant expressed in terms of capacitance of a capacitor?

Answer 1

Dielectric constant is equal to the ratio of the capacitance of a capacitor filled with the given material to the capacitance of an identical capacitor in a vacuum without the dielectric material.

K = capacitance of a capacitor with dielectric between the plates / capacitance of the same capacitor with vacuum/air in between the plates.

Answer 2

Answer: Dielectric constant of a medium is defined as the capacitance of a capactitor of (1/€) farad units, whose plates are unit distance apart and area havig unit meter square.

Explanation:As from formula

C = k€A/d, where k = dilectric

constant
