静电场中的电势

Potential in static Electric Field

在静电场中,电场强度和电势是描述电场性质的两个物理量。由于电场强度是矢量,电势是标量。用电势来分析、研究静电场就会显得简便。因此,对电势的概念的理解和电势的计算也就成了电磁学的主要内容之一。

Electric field intensity and potential in static field are two physic parameters by which the Properties of electric field are described. As electric field intensity is a vector and potential is a scalar quantity, it is easy to analyze and research static field by potential. It is one of main contents to understand and calculate potentail.
