Q&A
1. What are the dielectrics?
Dielectrics
are insulating materials, in which all the electrons are bound to their parent
molecules and there are no free charges. Even with normal voltage or thermal
energy, electrons are not released.
2. What are the types of
dielectrics?
Types of Dielectrics
Based
on the applications, there are two types of dielectric materials.
(i)
Active dielectrics (Ferroelectrics,
piezoelectrics and pyroelectrics).
(ii
)Passive dielectrics (electrical
insulating materials)
3. What are active dielectrics?
Active
dielectrics are the materials which are used to generate, amplify, modulate and
convert the electrical signals. They are used to store electrical energy.
4. What are passive dielectrics?
The function of the insulating material is to obstruct the flow of electric current.
