一、复习指要《电场》主要是研究电场的基本性质和规律,以及它们的应用.它首先研究了电荷相互作用的规律——库仑定律,在此基础上引入电场概念,并着重研究了表征电场性质的物理量——电场强度和电势,以及形象表示它们的电力线和等势面.最后对电场导体的静电平衡和电容器的电容作了简要的研究.在掌握《电场》知识结构中,还应注意电场知识和力学知识有着密切的联系,以利于掌握和运用电场的性质和规律.
First, review refers to “electric field” is mainly to study the basic properties and laws of electric fields, and their applications. It first studied the law of charge interaction - Coulomb’s law, based on the introduction of electric field concept, and focused on the study of the characterization The physical properties of the electric field—the electric field strength and electric potential, and the appearance of their electric lines and equipotential surfaces. Finally, the electrostatic balance of the electric field conductor and the capacitance of the capacitor were briefly studied. In the mastery of the “Electric Field” knowledge structure, Note that there is a close relationship between electric field knowledge and mechanics knowledge in order to facilitate the mastery and application of electric fields.
