Charging of Battery and Discharging of Battery

Before going in detail of this subject i.e. charging and discharging of battery , we will first try to understand what is oxidation and reduction. Because, battery are discharged or charged due to oxidation and reduction reactions. For understanding the theory of oxidation and reduction, we can dire

Voltaic Cell Basic Construction and Working of Voltaic Cell

A simple voltaic cell is made by immersing one zinc plate and one copper plate inside a water diluted sulfuric acid solution. As shown in the figure, if the copper plate and zinc plate are connected externally with an electrical load, an electric current starts flowing from copper plate to zinc plat

Electronic Polarization

As due to influence of external electric field the center of nucleus and center of electrons cloud are separated, there will be an attraction force developed between them according to Coulomb’s law . Say, at the distance of separation of center of nucleus and electron cloud, x, the equilibrium is es

Orientational Polarization

Before discussing Orientational polarization , let us examine the structural details of some molecules. Let us take an oxygen molecule. A single oxygen atom has only 6 electrons on its outermost cell. One oxygen atom creates the double covalent bond with another oxygen atom and creates an oxygen mol

Ionic Polarization

Ionic Polarization Before understanding what ionic polarization let is us observe how a sodium chloride (NaCl) molecule is formed. Sodium chloride (NaCl) molecule is formed by ionic bond between sodium and chlorine atoms. The sodium atom gives up one electron to get eight electrons in its outer most

Mechanism of Polarization

First of all we have to know the definition of polarization before entering into mechanism. Polarization is actually the alignment of the dipole moments of the fixed or induced dipole in the direction of the peripheral electric field . The mechanism of polarization deals with how a molecule or atom

Dielectric Materials: Definition, Properties and Applications

A dielectric material is defined as an electrical insulator that can be polarized by an applied electric field . This means that when a dielectric material is placed in an electric field, it does not allow electric charges to flow through it, but instead, it aligns its internal electric dipoles (pai
