教你一手在这个专题里,我们探讨有关静电场的一些重要原理以及场强、电势和电荷分布等问题的处理方法.相对于观察者静止的电荷所产生的电场被我们称为静电场,静电场最重要的外观表现一是对进入电场的任何带电体都产生力的作用;一是当带电体在电场中移动时,电场力做功,说明静电场具有能量.电荷守恒定律、库仑定律、高斯定理、场叠加原理、唯一性原理都是反映静电场这两大表现所具性质的基本规律.在摩擦起电、接触起电、感应起电或其他方法使物
Teach you a lesson In this topic, we explore some important principles about electrostatic fields and how to deal with such problems as field strength, potential and charge distribution. The electric field generated by static charges relative to the observer is what we call an electrostatic field, static electricity One of the most important appearances of the field is to exert a force on any charged body entering the electric field. The first is that when the charged body moves in the electric field, the electric field forces work, indicating that the electrostatic field has energy. The law of conservation of charge, Coulomb’s law, Gauss’s theorem , Field superposition principle, the only principle is to reflect the electrostatic properties of these two basic characteristics of the law.Friction in the friction, contact electrification, induced electromotive or other methods to make objects
