摘要
任一孤立导体及任一电容器具有不变的常数电容C,其电容大小由几何形状和几何尺寸决定,通常认为这是孤立导体和电容器自身的性质.从电容存在的物理本质进行的研究表明,由于平衡导体任意两点电荷密度之比具有守恒性及场强叠加原理,才确立了常数C.
Isolated conductor and any capacitor possess an unchaged constant capacity C, the capacitive size depends on its geometry shape and geometry measure. It is usually thought to be nature of isolated conductors and capacitors. This essay mainly discusses the physical nature existing electric capacity. The constant C is determined by the conservation of the electric charge density between any two points in balanced conductor and the superposition principle of electric field intensity.
