| Ngokungafani nama-voltage detectors, ama-voltage tester kufanele athintane nomthombo wamandla ukuze asebenze. Izihloli zamandla kagesi zinama-probe ensimbi afakwe kumjikelezo kagesi. I-voltage ihlolwe ngokuhambisana nesifunda, ngakho umhloli akuyona ingxenye edingekayo yesifunda. Ukhohlwe ukuthi "parallel" kusho ukuthini? Bona: Isifundo sikagesi sikaWonka Donka. |
 | Abahloli bamandla kagesi bathatha ukufundwa kwangempela kwamandla kagesi futhi bakunike ububanzi bezinombolo ongasebenza nabo kunokuba nje bathole ukuba khona kwamandla kagesi. |
inkomba |
| Abahloli bamandla kagesi banganikeza inani elinembile lenombolo uma benesikrini, kodwa ngokuvamile izinkomba zenziwa ngendlela yesikali se-LED. Lesi sikali sizonikeza ububanzi, hhayi inombolo eqondile, ye-voltage. |
| Ngakho-ke, isibonelo, kungase kube nama-LED abhalwe ukuthi 6, 12, 24, 60, 120, 230, no-400. Khona-ke uma uhlola okuthile nge-voltage engu-30, ama-LED 6,12, 24, no-24 azokhanya; okubonisa ukuthi une-voltage ephakathi kuka-60 no-XNUMX. Qiniseka ukuthi ubheka imiyalo yemodeli ngayinye ukuze ubone ukuthi isebenza kanjani. |
Izihloli zama-voltage zingasetshenziselwa ini? |
| Izihloli zamandla kagesi zingasetshenziselwa kokubili i-DC kanye ne-AC voltage, ngakho-ke kungenzeka ukuhlola amabhethri ngesihloli se-voltage. Ngokufana nomtshina we-voltage, lawa madivaysi angasetshenziswa futhi ukuhlola amasokhethi kanye nama-circuit breaker. Kodwa-ke, bangahlola ngokungeziwe ukuqhubeka kanye ne-polarity ngoba bane-probe ephindwe kabili futhi baxhumene nesekethe. |
