How Energy Stored in a Capacitor
The capacitor is a charge storage device. Work has to be done to store the charges in a capacitor. This work done is stored as…
Physics
Applications of Capacitors
The capacitor is the mechanical device designed to sustain the capacitance. Capacitor stores energy from a source such as electric cell and again uses it.…
What is Polarization of Dielectric Material?
Polarization of Dielectric Material: Consider a parallel plate capacitor with +q and –q charges. Fig: Polarization of dielectric material Let E0 be the electric field…
What is Polarization?
The alignment of the dipole moments of the permanent or induced dipoles in the direction of applied electric field is called polarization or electric polarization.…
What is Dielectrics?
A dielectric is an insulating material in which all the electrons are tightly bound to the nucleus of the atom. There are no free electrons…
