What is the charge? Why there are two kinds of charges? Why do the same charges repel, and dissimilar charges attract each other? Why meet the Coulomb's Law? These are the most basic questions of physics. Assume the existence of a kind microparticles in the universe, called electon casually; if an object contains electons more than its expected value, in the surplus state, and positively charged; if an object contains electons less than the expected value, in the scant state, and negatively charged; if an object contains electons equal to its expected value, in the saturated state, and is neutral. The charged objects have the property exchanging charged or uncharged microparticles in order to achieve the neutral state. The acting force between two charged objects comes from the exchange of charged and uncharged microparticles. The same charges repel, and dissimilar charges attract each other. The value of force is consistent with Coulomb's Law. The material between two charged objects affects the value of the acting force between them, but does not affect the direction.
