چکیده
That is, the electric potential difference is the work that must be done, per unit charge, to move from to with no change in kinetic energy. Remember not to confuse electric potential energy ∆ which is in joules, and electric potential difference ∆ which is in units of = The electric field is perpendicular to equipotentials, that is lines of constant electric potential. In fact, one can express the electric field as minus the gradient of the electric potential:

Chapter 6 ELECTRIC FIELDS IN DIELECTRICS
The discussion of electric fields has ignored the influence of matter on the field except for the discussion of fields in electric conductors. The behavior of matter in electric fields can greatly influence the field as shown for the case of a good conductor. The response of matter to an electric field falls into two main categories, polarization of bound charges in atoms or molecules, an...
متن کاملBlow-up of Electric Eields between Closely Spaced Spherical Perfect Conductors∗
In the present work, we derive that electric fields blow up as a pair of spherical perfect conductors approach each other, and calculate the blow-up rate by a simple method. In the case of two dimensional space, referring to an anti-plane shear model, we can assume that the conductors and the electric fields represent the cross-sections of parallel stiff fibers and the stresses, respectively. H...
متن کاملBlow-up of Electric Fields between Closely Spaced Spherical Perfect Conductors∗
In the present work, we establish an optimal estimate for the electric potential difference between closely adjacent spherical perfect conductors in n dimensional space (n ≥ 2). This result indicates that electric fields blow up as a pair of spherical perfect conductors approach each other, and provides the lower bound with the optimal blowup rate which was recently established by Bao, Li and Y...
متن کاملA New Method for Calculating of Electric Fields Around or Inside Any Arbitrary Shape Electrode Configuration
In this paper a new method for calculating of electric fields intensity around or inside any arbitrary shape electrode systems or conductors with the same or different configuration have been presented. As we know that in design and construction of a high voltage equipment, analysis of electric field intensity around and or inside that equipment has very important role therefore, according to p...
متن کاملDephasing in Disordered Conductors due to Fluctuating Electric Fields
We develop a novel eikonal expansion for the Cooperon to study the effect of spaceand time-dependent electric fields on the dephasing rate of disordered conductors. For randomly fluctuating fields with arbitrary covariance we derive a general expression for the dephasing rate which is free of infrared divergencies in reduced dimensions. For time-dependent external fields with finite wavelength ...
