参考答案:
(1) Dielectrics do not break down (allowing electric charge to flow) as readily as air, so a higher voltage can be applied without charge passing across the gap.
(2) A dielectric allows the plates to be placed closer together without touching thus allowing an increased capacitance because the plate separation is less.
(3) If a dielectric fills the space between the two conductors, it increases the capacitance.
