Expert Answer:

Why dielectric constant of an insulator is>1?

Dielectric constant is the ratio of electric field E_o through the region without the presence of the dielectrcic and electric field E in the presence of dielectric. 

E_o/E = K , Dielectric constant

since E_o is always greter than E, K alwys comes out to be >1
