FAQs on Dielectrics & Polarization Video Lecture - Physics for JEE Main & Advanced
| 1. What is the definition of a dielectric? |  |
Ans. A dielectric is a material that does not conduct electricity and is used to separate electrical charges in a capacitor. It is an insulating material that can be polarized when subjected to an electric field.
| 2. How does polarization occur in a dielectric? | |
Ans. Polarization in a dielectric occurs when the electric field causes the charges within the material to align themselves in a particular direction. This alignment creates an induced dipole moment, resulting in the polarization of the dielectric.
| 3. What is the role of dielectrics in capacitors? | |
Ans. Dielectrics play a crucial role in capacitors by increasing the capacitance of the device. When a dielectric material is placed between the capacitor plates, it reduces the electric field strength, allowing more charge to be stored for a given voltage.
| 4. What factors affect the polarization of a dielectric? | |
Ans. Several factors influence the polarization of a dielectric, including the magnitude of the electric field, the nature of the dielectric material, and the temperature. A stronger electric field, higher dielectric constant, and lower temperature generally lead to a higher degree of polarization.
| 5. Can dielectric polarization be permanent? | |
Ans. No, dielectric polarization is usually temporary and disappears when the electric field is removed. However, some dielectric materials, such as ferroelectric materials, can exhibit permanent polarization due to the presence of spontaneous electric dipoles that remain even in the absence of an external electric field.
