Ujongana njani ne-PCB uphawu lokuwela umgca wesahluli?
Kwinkqubo yoyilo lwePCB, ulwahlulo lwendiza yamandla okanye ulwahlulo lwenqwelomoya ephantsi kuya kukhokelela kwinqwelomoya engaphelelanga. Ngale ndlela, xa umqondiso uhanjiswa, inqwelomoya yayo yereferensi iya kudlula ukusuka kwinqwelomoya yamandla ukuya kwenye inqwelomoya yamandla. Le nto ibizwa ngokuba kukwahlulwahlulwa kobude bomqondiso. ...Funda ngokugqithisileyo -
