Why Do We Use Dielectric Material In Capacitor?
Dielectrics are used in capacitors in order to increase the capacitance. This is because dielectrics increase the ability of the medium between the plates to resist ionization, which in turn increases the capacitance. ... This accrues a net positive charge on the side of the dielectric facing the object and, consequently, a net negative charge ...

Capacitors Basics
What are capacitors? In the realm of electrical engineering, a capacitor is a two-terminal electrical device that stores electrical energy by collecting electric charges on two closely spaced surfaces, which are insulated from each other. The area between the conductors can be filled with either a vacuum or an insulating material called a dielectric.

What are some ways to increase the capacitance of a capacitor?
The capacitance of a capacitor can be increased by: 1. Increasing the surface area of the plates: The larger the area of the plates, the more charge they can store, thus increasing the capacitance. 2. Decreasing the distance between the plates: The closer the plates are to each other, the stronger the electric field between them, which increases the capacitance.
