PPT-Thermodynamic relations for dielectrics in an electric field

Section 10 Basic thermodynamics We always need at least 3 thermodynamic variables One extrinsic eg volume One intrinsic eg pressure Temperature Because of the equation of state only 2 of these are independent. 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.
