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
Consider a dielectric placed in an external electric field E0 (say between the plates of a charged capacitor). Due to external field, there will be
Static dielectric constant Definition: The ratio of the capacitance of a given capacitor (with the material filling the entire space between its plates) to the
Electric field between two oppositely charged parallel plates: In the last article, I have explained and derived the expression for the capacitance of parallel plate
Parallel plate capacitor consists of two conducting plates parallel to each other and separated by a distance which is small compared with the dimensions of
Definition of current: Current is defined as the flow of charge per unit time. that is I = q/t There is flow of energy due
In the last article, I have discussed about the capacitor, capacitance and its units. Today let us discuss about the uses of capacitors. Uses Of
CAPACITOR It is a device capable of storing a huge amount of electrical charges on its plates. Thus it is a device for storing energy
