PPT-The electric field in dielectrics

Section 6 Dielectrics C onstant currents are impossible Constant internal electric fields are possible No macroscopic currents Macroscopic field Might be locally nonzero Neutral dielectric Includes only charges belonging to dielectric namely electrons and protons of neutral constituent atoms. Dielectrics are the materials having electric dipole moment . permantly. .. Dipole:. A dipole is an entity in which equal positive and negative charges are separated by a small distance...

A capacitor consists of 2 conductors of any shape placed near one another without touching.. It is common to fill up the region between these 2 conductors with an insulating material called a dielectric.. Capacitor. A . capacitor. is an electrical device that stores energy. Most electrical devices have some capacitance either intentional or accidental . The . energy is stored by maintaining a potential difference between two conductors. Qiliang Li.

In dielectric materials, all the electrons are tightly bound to their parent molecules and there are no free charges.. Section 10. Basic thermodynamics. We always need at least 3 thermodynamic variables. One extrinsic, e.g. volume. One intrinsic, e.g. pressure. Temperature. Because of the equation of state, only 2 of these are independent.
