實驗表明，磁場和電場一樣也具有疊加的性質，描述磁場性質的物理量磁感應強度也遵從疊加原理。即任意載流導線在點的磁感應強度，等于所有電流元在點的磁感應強度的矢量和。這就是磁感應強度疊加原理的內容。寫成等式，得畢—薩定律是在實驗基礎上經過科學抽象提出來的，它不能用實驗直接驗證。 電工電線電纜載流量計算估算口訣二點五下乘以九，往上減一順 走。三十五乘三點五，雙雙成組減點五。條件有變加折算，高溫九折銅升級。穿管根數二三四，八七六折滿載流。說明：本節口訣對各種絕緣線（橡皮和塑料絕緣線）的載流量（電流）不是直接指出，而是“截面乘上一定的倍數”來表示，通過心算而得。 檢查操作電壓應大于85%Ue。四：分勵脫扣器不能使斷路器斷開產生原因：無電源電壓；電源容量不夠。排除方法：檢查線路，接通電源。檢查操作電壓應大于85%Ue。五：故障電流均超過長延時、短延時時、瞬時整定值、只出現瞬時動作，無短延時、長延時動作產生原因：長延時、短延時、瞬時整定值設定不合理，整定在同一電流值范圍。

同時，電容C被迅速充電，使它的兩端電壓也達6V。這個電路，按一下按鈕開關S，燈亮20秒左右自動熄滅(延時時間的長短可調節電容C的容量)，可做走廊照明燈的控制裝置。這個實例告訴我們，利用繼電器可以低電壓(6V)、弱電流(幾十毫安)來控制高電壓(220V)、強電流(幾百毫安)的電路。

瞬間高壓會擊穿超過耐壓的電子器件，甚至超過器線圈本身的耐壓使線圈損壞。為了消除此影響，可以采取如下方法：1、在線圈兩端并聯電阻并聯電阻使線圈在突然斷電時仍有電流通路，這樣就降低了電流變化率，使自感電動勢下降。

(：)這里需要注意的就是時間繼電器的觸點，帶有延時的觸點，是得電延時還是失電延時，一定要記牢才行，上學到的一個口訣，記住了也就好處理了。左凸右凹，延頭瞬尾；左凹右凸，瞬頭延尾；凹凸都有，延頭延尾；NONC看常態。 二次回路由電流互感器的二次線圈、儀表以及繼電器的電流線圈串聯組成。電流互感器大致可分為兩類，測量用電流互感器和保護用電流互感器。電流互感器的原理是依據電磁感應原理，它的一次繞組經常有線路的全部電流流過，電流互感器在工作時，它的2次回路始終是閉合的，因此測量儀表和保護回路串聯線圈的阻抗很小，電流互感器的工作狀態接近短路。
