Electric field lines and equipotential surfaces of single charge Electric field lines and equipotential surfaces of two charges 补一个偶极子(Dipole)的定义:偶极子是两个大小相等正负相反的电荷组成的系统。 总结练习a和b:等势线垂直于电场线,因为我们知道电势是电场强度的负梯度,也就是竖着的平行的几条线。
Work done by electric force is directly related to voltage. The higher the voltage, the more work is done by the electric force. This is because voltage is a measure of the electric potential energy per unit charge, and work is the transfer of energy. ...
Tags Charge Physics Potential Work Work done In summary, the conversation discusses the calculation of potential and potential difference between two points due to an electric charge, as well as the change in electric potential energy and the work done by the electric field. The solutions provided...

are oriented with their oxygen atoms pointing into the vacuum; hence as for a metal surface, there is an electric dipole that points from the vacuum towards the water; the dipole potential at the surface of water is estimated from experiment to be 20 mV (see Section 10.1 and Problem 10.1)...
Work,Energy and Power Work, Energy and Power Work Done by a force is defined as the product of the force and displacement (of its point of application) in the direction of the force W = F s cos θ Negative work is said to be done by F if x or its compo. is anti-parallel to ...

Field emission:This is the process of emitting electrons from a metal surface when it is subjected to a strong electric field. The work function and electric field are critical parameters in determining the amount and direction of emitted electrons. The electric field lowers the potential barrier ...
