电场强度是反映电场性质的物理量,是电场中最基本、最重要的概念之一,也是高考的热点.所以理解和掌握好“场强”这个概念极为重要,是掌握好电学许多重要概念的基础.求解电场强度的基本方法有:定义法E=F/q、真空中点电荷场强公式法E=kQ/r~2、匀强电场公式法E=U/d、矢量叠加法E=E_1+E_2+E_3……等.近几年的高考中,计算电场强度时,必须要注重
Electric field strength is a physical quantity that reflects the nature of the electric field and is one of the most basic and important concepts in the electric field and also a hot spot in the college entrance examination.Therefore understanding and mastering the concept of field strength is extremely important to master many important concepts The basic method of solving the electric field strength are: the definition of the law E = F / q, the vacuum midpoint charge field strength formula E = kQ / r ~ 2, uniform electric field formula E = U / d, vector superposition method E = E_1 + E_2 + E_3 ...... Etc. In recent years, college entrance examination, the calculation of electric field intensity, we must pay attention
