1、周期、和角簡諧交流電完成一次周期性變化所用的時間叫周期，用表示，它是波形重復出現的短時間。單位時間內簡諧交流電完成周期性變化的叫，用表示，單位：赫茲（）。它與周期的關系或及其他多數國家發電廠發出的交流電的為50Hz，通常稱為“工頻”，也有的國家采用60Hz的。
當放開按鈕后，由電源提供電流IB的電路被切斷，但電容C兩端存在電壓，還能維持晶體管工作，隨著時間的，電容中的電荷經過電阻R與晶體管的發射結泄放，電容兩端的電壓逐漸下降，當晶體管UBE0.5V以后，VT截止，繼電器線圈失去電壓而釋放，觸點被打開，“220V、40W”燈泡的電源被切斷而熄滅。 交流器上標的A1、A2，就是它的工作線圈，是接電源用的，有一定電壓等級，一般有標在旁邊，如：220V，你給它接上220V電源，它就工作，觸點就閉合。線圈A1、A2接點：線圈A1、A2是器線圈的兩個接線端，與交流電源相連，通電就產生電磁吸合，使器的觸點系統動作。

而蓖麻抽因e大，在脈沖電容器中得到了應用。三氯聯苯電氣性能較.但由于它具有性而被淘汰.。材料三:電極材科大部分的電極材料都是鋁箔，在并聯低壓電容器中，也有用金屬化的方式作為電極。這個沒有什么好講的,因為性價比的關系,現在鋁箔已經被大量并且廣泛運用在電力電容器的生產材料中.。 軌道交通等行業都有新產品需求，"上述某企業高層表示，其所在企業主要靠加強內部管理，成品率來保證產品利潤，[如果產品出現質量問題，維修成本更高，對產品質量問題的也很嚴厲，當前我們主要通過精細化管理降低成本。
