網頁Electric charge is the property of objects that gives rise to this observed force. Like gravity, electric force "acts at a distance". The idea that a force can "act at a distance" is pretty mind-blowing, but it's what nature really does. Electric forces are very large, far greater than the force of gravity. 網頁A conductor is a material that allows electrons to flow freely through it, making it useful for carrying electric current. An insulatoris a material that resists the flow of electrons, so it does not allow electric current to pass through it. Learn about how conductors and insulators work and how they are effected by changes in electrical current. 網頁爱词霸权威在线词典,为您提供charge的中文意思,charge的用法讲解,charge的读音,charge的同义词,charge的反义词,charge 的例句等英语服务。爱词霸英语为广大英语学 … hanamint logo on patio furniture
