Effect of dielectric on Capacitance
Effect of dielectric on Capacitance
When a dielectric is present between the plates of a parallel plate capacitor fully occupying the region , the dielectric is polarized by the electric field . The surface charge densities are considered as σ p and -σ p .
Dielectric constant of a substance is the factor by which the capacitance increases from its vacuum value , when the dielectric is fully inserted in between the plates of the capacitor
