电场强度与电势是研究电场性质的两个重要的物理量,电场强度描述电场的力的性质,而电势描述电场能的性质,它们既有着紧密的联系,又有着严格的区别。然而对于高中生来说,由于对基本概念的模糊不清,尤其是对两者关系理解的不透彻,常常得到一些似是而非的结论。笔者从公式E=U/d入手,详细分析两者之间的联系,并在此基础上加
Electric field strength and electric potential are two important physical quantities for studying the properties of electric field. Electric field strength describes the force properties of electric field, while electric potential describes the properties of electric field energy. They have both close relationship and strict distinction. However, for high school students, some of the specious conclusions often come to light due to the vagueness of the basic concepts and, in particular, the lack of thorough understanding of the relationship between the two. I start from the formula E = U / d, a detailed analysis of the link between the two, and on this basis, plus
