EFFECT OF DIELECTRIC IN A CAPACITOR

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

Electric field inside a dielectric

Why does the electric field inside a dielectric decrease when it is placed in an external electric field? (Thushara asked) Answer: The net electric field inside a dielectric decreases due to polarization. The external electric field polarizes the dielectric and an electric field is produced due to this polarization. This internal electric field will be…… Continue reading Electric field inside a dielectric
