What is the effect of dielectric medium in comparison to vacuum on electric field and electric flux?
permittivity relates to a material's ability to resist an electric field (while, unfortunately, the word stem "permit" suggests the inverse quantity).

Therefore, higher dielectric constant means higher relative permittivity which means more resistance to the electric field.
But a higher dielectric constant means an increase in electric flux which leads to a higher capacitance!
Please explain the resistance to the electric field with an increase in electric flux?
