What is a Dielectric?
Non-conducting materials are known as dielectrics. They are insulating materials and poor electric current conductors. Dielectric materials can maintain an electrostatic charge while losing very little energy as heat. Mica, plastics, glass, porcelain, and other metal oxides are examples of dielectrics. It’s also important to note that even dry air is dielectric.
Dielectrics and Polarisation
Have you noticed how many of the insulators are made of wood, plastic, or glass? But why is that? When we utilise wood or plastic, why don’t we receive electric shocks? Why do you only get severe shocks from metal wires? We’ll look at dielectrics, polarisation, the dielectric constant, and more in this chapter. We’ll look at some typical applications and examples of these dielectrics as well.
