Consider a parallel plate capacitor. When half of the space between the plates is filled with some dielectric material of dielectric constant K as shown in Fig. (1) below, the capacitance is C₁ . However, if the same dielectric material fills half the space as shown in Fig. (2), the capacitance is C₂ . Therefore, the ratio C₁: C₂ is
