Electricity is an important part of all substances. Usually, equal amounts
of positive and negative electricity are present and cancel each other's
effect, and so we do not notice that any electricity is there at all.
But when the positive and negative parts are separated in some way, we see their
effects and recognize that electricity is present. When, for instance, an
ebonite fountain pen is rubbed with a silk handkerchief some of the
atoms in the silk have one or two of their electrons knocked off.

電力是一種非常重要的物質. 通常我們無法感覺到電力存在是因為等量的正負電相互抵消彼此的效力. 但是,當我們將正負電分離後,就可以理解電力的存在.舉例說明,當使用絲質手帕磨擦塑膠原子筆時,
(最後一句是不是有打錯,還是少打了逗號?)
絲布上的一些原子會被敲落一到兩個電子下來.

電是所有物質的一重要部份。通常, 相等的相當數量正面和消極電是存在和取消彼此的作用, 和因此我們不注意任一電是那裡根本。但當正面和消極零件被分離得在某個方面, 我們看他們的作用和認為, 電是存在。例如, 硬橡膠鋼筆用一張絲綢手帕被摩擦一些原子在絲綢有一兩他們的電子被敲。
