What is dielectric constant for an insulating medium?

The dielectric constant of an insulator in a transmission line is 2.25. Calculate velocity factor of the transmission line

For metals the value of dielectric constant (K) is

If K is the dielectric constant of the medium. A is area of insulated charged plates and d is the distance between two plates of parallel plate condenser then its capacity in CGS unit is

If the dielectric constant and dielectirc strength be denoted by K and x respectively, then a meterial suitable for use as a dielectric in a capacitor must have

The space between parallel plate capacitors is filled with four dielectrics of equal dimensions but of dielectric constants K_(1), K_(2), K_(3)andK_(4) respectively. If K is the dielectric constant of a single dielectric that must be filled between capacitor plates to have the same capacitance between A and B. Then we must have

A parallel plate capacitor having a separation between the plates d, plate area A and material with dielectric constant K has capacitance C_(0) . Now one-third of the material is replaced by another material with dielectric constant 2K, so that effectively there are two capacitors one with area 1/3A, dielectric constant 2K and another with area 2/3A and dielectric constant K. If the capacitance of this new capacitor is C then (C)/(C_(0) is
