particle's electrical potential energywork-energy theoremThis chapter deals with concepts of importance to dielectrophoresis, namely the work done and the potential energy associated with interactions between charged particles and electric fields. The concept of electrical potential energy can be applied to...
静电势能(electrostatic potential energy)静电势能是把一个电荷从无穷远处移动到这个位置需要做的功。 静电势能的符号: U 图示: 计算公式: U =\frac{q_1q_2}{4\pi\epsilon_0R} \\其中 U 是静电势能,单位焦耳q…
In Electric Charge and Electric Field, we just scratched the surface (or at least rubbed it) of electrical phenomena. Two of the most familiar aspects of electricity are its energy and voltage. We know, for example, that great amounts of electrical energy can be stored in batteries, are tr...

Point A is at an electric potential of +75V and point B is at an electric potential at -75V. The work done by an external force to move a charge from A to B is 7.5 x 10-4J. If the charge starts from rest at A and has kinetic energy of 2.4 x 10-4J when it reaches B, wh...
This is the electric potential energy per unit charge. V=PEqV=PEq Since PE is proportional toq, the dependence onqcancels. ThusVdoes not depend onq. The change in potential energy ΔPE is crucial, and so we are concerned with the difference in potential or potential difference ΔVbetween tw...
If V and u are electric potential and energy density, respectively, at a distance r from a positive point charge, then which of the following graph is correct
The electric potential energy is a form of potential possed by a charged object by the virtue of its position in an electric field. In order to move a charged object from one point to another in an electric field without changing its kinetic energy, work must be done on the...
