充電器上寫的AC跟DC是什么意思?
充電器(qi)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(shi)什么意(yi)思?
AC代表(biao)的是“交(jiao)(jiao)(jiao)流(liu)(liu)(liu)電(dian)(dian)(dian)”,交(jiao)(jiao)(jiao)流(liu)(liu)(liu)電(dian)(dian)(dian)也稱(cheng)“交(jiao)(jiao)(jiao)變電(dian)(dian)(dian)流(liu)(liu)(liu)”,簡(jian)稱(cheng)“交(jiao)(jiao)(jiao)流(liu)(liu)(liu)”。強度與方向都(dou)隨時間(jian)做周期性變化的電(dian)(dian)(dian)流(liu)(liu)(liu)叫做交(jiao)(jiao)(jiao)變電(dian)(dian)(dian)流(liu)(liu)(liu),簡(jian)稱(cheng)交(jiao)(jiao)(jiao)流(liu)(liu)(liu)電(dian)(dian)(dian)。電(dian)(dian)(dian)流(liu)(liu)(liu)方向隨時間(jian)作周期性變化的為交(jiao)(jiao)(jiao)流(liu)(liu)(liu)電(dian)(dian)(dian)。中國通常使用(yong)的交(jiao)(jiao)(jiao)流(liu)(liu)(liu)電(dian)(dian)(dian),一般頻率(lv)是50Hz。我們常見(jian)的電(dian)(dian)(dian)燈、電(dian)(dian)(dian)動(dong)機等用(yong)的電(dian)(dian)(dian)都(dou)是交(jiao)(jiao)(jiao)流(liu)(liu)(liu)電(dian)(dian)(dian)。在實(shi)用(yong)中,交(jiao)(jiao)(jiao)流(liu)(liu)(liu)電(dian)(dian)(dian)用(yong)符號(hao)“~”表(biao)示。
2、DC是(shi)什么意思?
DC代表的(de)(de)是“直(zhi)流(liu)電(dian)(dian)(dian)(dian)”,又稱(cheng)“恒流(liu)電(dian)(dian)(dian)(dian)”,恒定(ding)電(dian)(dian)(dian)(dian)流(liu)是直(zhi)流(liu)電(dian)(dian)(dian)(dian)的(de)(de)一種,是大(da)小和方(fang)向都不(bu)變的(de)(de)直(zhi)流(liu)電(dian)(dian)(dian)(dian)。恒定(ding)電(dian)(dian)(dian)(dian)流(liu)是指大(da)小(電(dian)(dian)(dian)(dian)壓高低)和方(fang)向(正負(fu)極)都不(bu)隨時間(jian)(相對范圍內)而變化,比如干電(dian)(dian)(dian)(dian)池。直(zhi)流(liu)電(dian)(dian)(dian)(dian)是電(dian)(dian)(dian)(dian)荷的(de)(de)單向流(liu)動或者移動,通(tong)常是電(dian)(dian)(dian)(dian)子(zi)。電(dian)(dian)(dian)(dian)流(liu)密度隨著時間(jian)而變化,但是通(tong)常移動的(de)(de)方(fang)向在所有時間(jian)里都是一樣的(de)(de)。作為(wei)一個(ge)形容(rong)詞,DC可用于參考電(dian)(dian)(dian)(dian)壓(它的(de)(de)極性永(yong)遠不(bu)會(hui)改變)。
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。
