Dielectric Materials A dielectric is an electrical insulator that can be polarized by an applied electric field. When a dielectric is placed in an electric field, electric charges do not flow through the material as they do in a conductor, but only slightly shift from their average equilibrium positions causing dielectric polarization. Because of dielectric… Read More »
What is a Capacitor? Capacitor is a device that stores electric charge. A capacitor consists of two conductors separated by an insulator. Capacitors have many applications some of them include Computer RAM memory and keyboards, Electronic flashes for cameras, Electric power surge protectors and Radios and electronic circuits. Another definition of capacitor can be that… Read More »
