Dielectric Materials and Polarization Chapter 6

In the case of a metal, an applied electric field will induce a current composed of the freely mobile electrons. In an insulator, or dielectric, some-thing else must happen because there are no free electrons. What can, and does, happen is that the electric field pulls the electron and pushes the positively charged nucleus.

18.5 Capacitors and Dielectrics

The word dielectric is used to indicate the energy-storage capacity of a material. Remind students that insulator is used to indicate the ability of a material to prevent the passage of electric charge. [BL] [OL] Point out that the prefix di means two or double. Combined with the word electric, this implies that a dielectric can have two electric charges. [AL] Ask students whether they know of

Effect of Dielectric on Capacitance

When we put a dielectric slab in between two plates of a parallel plate capacitor, the ratio of the applied electric field strength to the strength of the reduced value of electric field capacitor is called the dielectric constant. It is given as. K = E o /E. E 0 is greater than or equal to E, where E o is the field with the slab and E is the field without it. The larger the dielectric

The capacitance does not change since it is a geometrical quantity. Given the area of the plates, the dielectric medium and the distance between the plates, capacitance is constant.

Another useful and slightly more intuitive way to think of this is as follows: inserting a slab of dielectric material into the existing gap between two capacitor plates tricks the plates into thinking that they are closer to one another by a factor equal to the relative dielectric constant of the slab.

6 FAQs about [What will happen if a dielectric is added to the solar panel ]

What happens when a dielectric is placed between charged plates?

When a dielectric is placed between charged plates, the polarization of the medium produces an electric field opposing the field of the charges on the plate. The dielectric constant k is defined to reflect the amount of reduction of effective electric field as shown below.

How does a dielectric polarize a material?

An applied electric field will polarize the material by orienting the dipole moments of polar molecules. This decreases the effective electric field between the plates and will increase the capacitance of the parallel plate structure. The dielectric must be a good electric insulator so as to minimize any DC leakage current through a capacitor.

Can a dielectric satisfy a polarization charge?

We introduced the dielectric constant and then the permittivity as a means of ignoring the polarization charge. That is, the capacitance with a dielectric still satisfies Q = CV, where Q is the charge on the plates, not the combination of the charge on the plates with the polarization charge.

Why is a dielectric a good insulator?

The dielectric must be a good electric insulator so as to minimize any DC leakage current through a capacitor. The presence of the dielectric decreases the electric field produced by a given charge density. The factor k by which the effective field is decreased by the polarization of the dielectric is called the dielectric constant of the material.

Why does a battery pull a dielectric?

This force exists purely due to the presence of charge on the plates, so the dielectric is pulled in whether the plates are being held at a constant potential difference by a battery or not.

What is a common application of dielectrics?

The most common application of dielectrics is in capacitors, as one would guess from the figure. How is the capacitance affected by the presence of this substance? Given the same charges on the plates, the polarization charge reduces the electric field between the plates compared to the vacuum case, so the voltage difference is decreased.
