摘要
为了促进学生对电容器所储电能与电场能量之间联系的学习理解,利用电场能量公式及电容器能量公式计算圆柱形电容器的电容,提供了计算电容的另一方法,并将该方法与保角变换法求电容加以比较;利用高斯定理及场强叠加原理计算圆柱形电容器各表面电荷分布,结果表明,所带电荷只分布在相对的两柱面上.
In order to promote the students＇ understanding of the relationship between the energy stored in the capacitor and the electric field energy,Using field energy formula and capacitor energy formula calculate the capacitance of cylindrical capacitor,provides a approach for capacitance calculation,and the method is compared with the conformal transformation method; The surface charge distribution of cylindrical capacitor is calculated by the Gauss theorem and the superposition principle of field strength. The results show that the charge is only distributed on the relative two cylinders.
