充電器上寫的AC跟DC是什么意思?

       充電器是為工具提供電量來源的一種電源,在我們日常生活中是必不可少的工具,像刮胡刀、手機、電腦等等都需要充電器,但是充電器一般都有很多參數,AC和DC就是其中的兩種,那么充電器上寫的AC和DC分別是什么意思呢?

1、AC是什么意思?

    AC代表的是“交(jiao)流電(dian)(dian)(dian)(dian)”,交(jiao)流電(dian)(dian)(dian)(dian)也稱(cheng)(cheng)“交(jiao)變電(dian)(dian)(dian)(dian)流”,簡(jian)稱(cheng)(cheng)“交(jiao)流”。強度與方(fang)向都隨(sui)(sui)時間做周期性變化的電(dian)(dian)(dian)(dian)流叫做交(jiao)變電(dian)(dian)(dian)(dian)流,簡(jian)稱(cheng)(cheng)交(jiao)流電(dian)(dian)(dian)(dian)。電(dian)(dian)(dian)(dian)流方(fang)向隨(sui)(sui)時間作周期性變化的為(wei)交(jiao)流電(dian)(dian)(dian)(dian)。中國通(tong)常使用(yong)的交(jiao)流電(dian)(dian)(dian)(dian),一般頻率(lv)是50Hz。我們常見的電(dian)(dian)(dian)(dian)燈、電(dian)(dian)(dian)(dian)動機等用(yong)的電(dian)(dian)(dian)(dian)都是交(jiao)流電(dian)(dian)(dian)(dian)。在實用(yong)中,交(jiao)流電(dian)(dian)(dian)(dian)用(yong)符號“~”表示(shi)。

2、DC是什么意(yi)思?

    DC代表的(de)(de)(de)是(shi)“直流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)”,又稱“恒流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)”,恒定電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)是(shi)直流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)的(de)(de)(de)一(yi)種,是(shi)大(da)(da)小和方(fang)向都(dou)不變(bian)(bian)的(de)(de)(de)直流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)。恒定電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)是(shi)指大(da)(da)小(電(dian)(dian)(dian)(dian)壓高低(di))和方(fang)向(正負極)都(dou)不隨(sui)時間(jian)(jian)(相對(dui)范圍內)而(er)變(bian)(bian)化(hua),比如(ru)干電(dian)(dian)(dian)(dian)池。直流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)是(shi)電(dian)(dian)(dian)(dian)荷(he)的(de)(de)(de)單向流(liu)(liu)(liu)(liu)動(dong)(dong)或者移動(dong)(dong),通(tong)(tong)常(chang)是(shi)電(dian)(dian)(dian)(dian)子(zi)。電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)密度隨(sui)著時間(jian)(jian)而(er)變(bian)(bian)化(hua),但是(shi)通(tong)(tong)常(chang)移動(dong)(dong)的(de)(de)(de)方(fang)向在(zai)所有時間(jian)(jian)里(li)都(dou)是(shi)一(yi)樣的(de)(de)(de)。作為(wei)一(yi)個形容詞,DC可用于(yu)參考電(dian)(dian)(dian)(dian)壓(它(ta)的(de)(de)(de)極性永遠不會改變(bian)(bian))。

    充電器上寫的AC和DC分別是什么意思?就分享到這里。實際上AC和DC的意思是很好理解的,就是代表了交流電和直流電。在使用充電器的時候除了要了解這些字母代表的意思之外,如何正確使用充電器也是非常的重要的,因為如果使用方法不當的話,就很有可能會損壞充電器,甚至引發安全事故,我們一定不能忽視。
