【Abstract】 Electrostatic field is a very important chapter in electromagnetics and the strength of electric field is one of the two basic physical quantities describing the property of electrostatic field. The counting of the strength of electric field is the key and difficult point in this chapter. In this essay we will discuss the three commonly used methods, steps and each one ’ s comparative advantages and shortages on counting the strength of electric field in electrostatic field.更多还原
