The capacitance of a parallel plate capacitor without any medium between its plates is given by When a dielectric completely fills the space between the plates of the capacitor, the capacitance increases K times, where K is the dielectric constant (relative permitivity) of the dielectric. If a dielectric slab of thickness t (<d) is introduced … Continue reading EFFECT OF DIELECTRIC IN A CAPACITOR
