人教版高中物理第2册电磁学部分内容中提到:“导体静电平衡时电荷分布在导体的外表面,导体内表面不带电”.这一结论可以用实验来验证.如果用口径不大的导体球壳和传电小球来演示,会存在两个不足:一是只能从导体球外表面让导体带电,这对说明电荷分布在导体外表面 PEP teach high school physics volume 2 Electromagnetics part of the reference: “Electrostatic charge balance of the conductor in the outer surface of the conductor on the surface without electricity ” This conclusion can be verified experimentally .If the caliber The small conductor sphere and the transmission ball to demonstrate, there will be two deficiencies: First, the conductor can only be charged from the outer surface of the conductor, which shows the charge distribution in the outer conductor surface
