電(dian)(dian)池(chi)和直(zhi)(zhi)流電(dian)(dian)源(yuan)是當今使用廣泛的(de)(de)電(dian)(dian)源(yuan)，廣泛應用于手機(ji)、相機(ji)、小家(jia)電(dian)(dian)甚至汽(qi)車。在電(dian)(dian)池(chi)生(sheng)成測(ce)試期(qi)間應監測(ce)電(dian)(dian)池(chi)容量，以(yi)確保(bao)產品性能。為了正確確定直(zhi)(zhi)流的(de)(de)持續時間，需要斷開電(dian)(dian)池(chi)與一(yi)定直(zhi)(zhi)流電(dian)(dian)流的(de)(de)連接，將(jiang)直(zhi)(zhi)流電(dian)(dian)源(yuan)的(de)(de)輸出電(dian)(dian)壓(ya)更(geng)改(gai)為電(dian)(dian)池(chi)的(de)(de)空載電(dian)(dian)壓(ya)，然后用電(dian)(dian)阻將(jiang)其連接到直(zhi)(zhi)流電(dian)(dian)源(yuan)，等于電(dian)(dian)池(chi)的(de)(de)內阻。

在傳統(tong)生產中，由于(yu)電(dian)(dian)(dian)池的(de)放(fang)電(dian)(dian)(dian)過程，電(dian)(dian)(dian)池端子處的(de)電(dian)(dian)(dian)壓(ya)進一步降低(di)。為了保持(chi)輸出電(dian)(dian)(dian)流(liu)，我(wo)們(men)必須(xu)不斷(duan)降低(di)放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)阻。手動控制(zhi)很難準確控制(zhi)，這時就可以(yi)使用電(dian)(dian)(dian)子負(fu)載CC模式解決了這個問題，減少了員工的(de)工作量，提高了檢測的(de)準確性。

線性負載：當(dang)施加可(ke)變(bian)正弦電(dian)(dian)(dian)壓(ya)(ya)時，負載阻(zu)抗參(can)數(z)為(wei)常數的負載。交流電(dian)(dian)(dian)路(lu)中的負載元件有(you)電(dian)(dian)(dian)阻(zu)R、電(dian)(dian)(dian)感L和(he)電(dian)(dian)(dian)容C三(san)種，它們在電(dian)(dian)(dian)路(lu)中的結(jie)果(guo)不同。在純電(dian)(dian)(dian)阻(zu)電(dian)(dian)(dian)路(lu)中，當(dang)電(dian)(dian)(dian)阻(zu)R上(shang)加正弦電(dian)(dian)(dian)壓(ya)(ya)U時，產生的電(dian)(dian)(dian)流I也是(shi)正弦的，電(dian)(dian)(dian)流I與電(dian)(dian)(dian)壓(ya)(ya)U的相(xiang)位(wei)相(xiang)同。如電(dian)(dian)(dian)壓(ya)(ya)U=umminωt。那么(me)I=imsinωt電(dian)(dian)(dian)流的有(you)效值I=u/R。電(dian)(dian)(dian)通過電(dian)(dian)(dian)阻(zu)產生熱量，電(dian)(dian)(dian)能轉化為(wei)熱能，即P=UI=I2R。

　交流(liu)電路中(zhong)的負載元件有電阻R、電感L和電容(rong)C三種，KPEL-M系列低電壓高(gao)電流(liu)直流(liu)電子負載，它們在(zai)電路中(zhong)的結果不同。

　在(zai)純電(dian)阻電(dian)路(lu)中，當(dang)電(dian)阻R上加正(zheng)(zheng)弦電(dian)壓U時，產生的(de)電(dian)流I也是(shi)正(zheng)(zheng)弦的(de)，電(dian)流I與電(dian)壓U的(de)相位相同。
