potential energy can be defined Change in electric potential energy is negative of work done by electric force: (17-1) 17.1 Electrostatic Potential Energy and Potential Difference Electric potential is defined as potential energy per unit charge: (17-2a) Unit of electric potential: the volt (V)...
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…
whether or not the charge moves, the electric potential energy of the a point is always greater than the electric potential energy of the B point Analysis: electric potential positive charge in high potential place has more and more high electric potential negative charge in places with less ...

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...
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...
2.电势能(electric potential energy)(1)定义:电荷在电场中具有的势能,叫做电势能,静电力做的功等于电势能的,用公式表示(2)电荷在某点的电势
6) Nernstian potential 能斯特电位补充资料:电位 描述电场的一个物理量。又称电势。是个标量。静电场中某点P 的电位φ,数值上等于单位正电荷处于该点时具有的位能,即单位正电荷从该点P 移至参考点Q 时电场力对它作的功,式中E 为电场强度, dl为积分路径上的线元。在国际单位制中,电位的单位为伏[特](...
在静电学里,电势能(Electric potential energy)是处于电场的电荷分布所具有的势能,与电荷分布在系统内部的组态有 关。电势能的单位是焦耳。电势能与电势不同。电势定义为处于电场的电荷所具有的电势能每单位电荷。电势的单位是伏特 。 如果核外电子绕核旋转半径是确定的,那么根据以上公式,连续X射线能Ex1应该等于用电...
