電荷既不能(neng)創造，也不能(neng)消滅(mie)，它(ta)只能(neng)從一(yi)個物(wu)體(ti)轉(zhuan)移到另一(yi)個物(wu)體(ti)，或者從物(wu)體(ti)的(de)一(yi)部(bu)分轉(zhuan)移到另一(yi)部(bu)分。在轉(zhuan)移的(de)過程(cheng)中，系統的(de)電荷總數保持(chi)不變 [3]  。

電荷具有實物的屬性，不能離開電子和質子而存在。使物體帶電的實質是獲得或失去電子的過程。起電的本質：都是將正、負電荷分開，使電荷發生轉移。實質是電子的轉移，并不是創造電荷。

電(dian)子(zi)(zi)(zi)(zi)（electron）是帶負電(dian)的(de)亞原子(zi)(zi)(zi)(zi)粒(li)子(zi)(zi)(zi)(zi)。它可以是自由的(de)（不屬于任何(he)原子(zi)(zi)(zi)(zi)），也可以被原子(zi)(zi)(zi)(zi)核束縛。原子(zi)(zi)(zi)(zi)中的(de)電(dian)子(zi)(zi)(zi)(zi)在(zai)(zai)各種各樣的(de)半徑和描述能量(liang)(liang)級別的(de)球形(xing)殼里存在(zai)(zai)。球形(xing)殼越大，包含在(zai)(zai)電(dian)子(zi)(zi)(zi)(zi)里的(de)能量(liang)(liang)越高。在(zai)(zai)電(dian)導體中，電(dian)流由電(dian)子(zi)(zi)(zi)(zi)在(zai)(zai)原子(zi)(zi)(zi)(zi)間(jian)的(de)獨(du)立(li)運動產生(sheng)，并(bing)通常從電(dian)極(ji)的(de)陰極(ji)到陽極(ji)。
