WebCalculate the electric density of the space. Energy Density in electric field is defined as the total energy per unit volume of the capacitor. Zeolites have small, fixed-size openings that allow small molecules to pass through easily but not larger molecules; this is why they are sometimes referred to as molecular sieves. Loop is uniformly rotating with angularvelocity in uniform magnetic field. For example, the number of calories per gram of food. :
_GL"$@3dD`L. A dielectric material gets polarized when it placed in an electric field. The field produce due to the polarization of material minimize the effect of external field. Hence, the electric field inside a dielectric decreases when it is placed in an external electric field. The electric field is a region of charge that is charged by an electrostatic force on other charges. The energy of an electric field generated by a free electric charge is determined by its electric flux density. Where, Ans. It is given as: E = F / Q. Therefore, the relation between current density and an electric field is JE.
