EQUATION OF CONTINUITY FOR TIME VARYING FIELDS: Statement: Equation of continuity represents the law of conservation of charge. That is the charge flowing out (i.e.
Ferroelectric materials and piezoelectric materials can be compared with the help of following points : a) In piezoelectricity, the crystal is polarized by the application
ferroelectric materials have following applications: (a) As Capacitors: Ferroelectric materials can be used to make capacitors. (b) As Varactors: The value of dielectric constant for
Ferroelectric materials can be classified on the basis of their chemical composition and structure as : (a) Rochelle salt: The first solid to show ferroelectric
In the last article, I have discussed about ferroelectricity and hysteriesis loop. Today we will discuss about the reason of hysteresis loop. Ferroelectric crystals have
Last time I have discussed about the piezoelectricity. Let us discuss about the applications of piezoelectric effect. (a) Electro-mechanical transducers. Piezoelectric effect is used to
Definition: When certain crystals become electrically polarized that is electric charges appear on their surface when stressed then this phenomenon is called the piezoelectric effect,
In the earlier article, I have explained the electronic polarization. Today we will discuss the ionic polarization. Ionic polarization. As the name suggests, ionic polarization
The four types of polarization which occur in dielectrics are: (I) Electronic polarization, (II) Ionic polarization, (III) Orientation or dipole polarization, (IV) Space charge or
Let us derive the relation between polarization vector (P), displacement (D) and electric field (E): In the last article of polarization, we have discussed about
