We therefore have the same equations for $kappaFLPE$ as for $FLPE_0$, so they have the solution $kappaFLPE=FLPE_0$. In other words, the field is everywhere smaller, by the factor $1/kappa$, than in the case without the dielectric. Since the voltage difference is a line integral of the field, the voltage is reduced by this same factor.
