电场是电磁学的基础 .电场看不见 ,摸不着 ,但具有力和能两方面的性质 .本章以电场力和电场能为两条主线 ,分别讨论了电场的性质 ,继而又讨论了电场中的导体、电容以及带电粒子在电场中的运动等问题 .而且还涉及平衡、加速、偏转、圆周运动等各类问题 ,解决问题用到几乎所有的? The electric field is the basis of electromagnetism. The electric field is invisible and intangible, but it has both force and energy properties. In this chapter, the electric field force and the electric field energy are the two main lines. The properties of the electric field are discussed separately, and then the electric field is discussed. Problems with conductors, capacitors, and motion of charged particles in an electric field. Also involved in various problems such as balance, acceleration, deflection, and circular motion. Almost all problems are solved.
