21. Imvamisa yesethi ye-generator izinzile, kepha i-voltage ayizinzile. Inkinga ilele enjinini noma ku-generator?

Impendulo: Ilele ku-generator.

22. Kwenzekani ekulahlekelweni kukazibuthe wejeneretha nokuthi ubhekana kanjani nakho?

Impendulo: I-generator ayisetshenziswa isikhathi eside, okwenza ukuthi i-remanence equkethwe kumnyombo wensimbi ilahleke ngaphambi kokushiya ifektri, futhi ikhoyili yokuthakazelisa ayikwazi ukwakha amandla kazibuthe afanele. Ngalesi sikhathi, injini isebenza ngokujwayelekile kepha awukho ugesi owenziwayo. Lolu hlobo lwesimo ngumshini omusha. Noma kunamayunithi amaningi angasetshenziswanga isikhathi eside.

Isixazululo: 1) Uma kunenkinobho yokuthakazelisa, cindezela inkinobho yokuzijabulisa;

2) uma kungekho nkinobho yokuthakazelisa, sebenzisa ibhethri ukuyifaka ngozibuthe;

3) layisha isibani esikhanyayo bese uyigijimisa ngesivinini esikhulu ngokweqile imizuzwana embalwa.

23. Ngemuva kokusebenzisa i-generator ebekiwe isikhathi esithile, kutholakala ukuthi konke okunye kujwayelekile kepha amandla ancipha. Siyini isizathu esiyinhloko?

Impendulo: a. Isihlungi somoya singcolile kakhulu futhi nomoya wokungenisa awenele. Ngalesi sikhathi, isihlungi somoya kufanele sihlanzwe noma sishintshwe.
b. Idivayisi yokuhlunga uphethiloli ingcolile kakhulu futhi nomthamo wokujova uphethiloli awwenele, ngakho-ke kufanele ushintshwe noma uhlanzwe.
c. Isikhathi sokushisa asilungile futhi kufanele silungiswe.

24. Ngemuva kokuthi isethi ye-generator ilayishiwe, amandla ayo kanye nemvamisa kuzinzile, kepha okwamanje akuzinzile. Yini inkinga?

Impendulo: Inkinga ukuthi umthwalo wekhasimende awuzinzile, futhi nekhwalithi ye-generator ilungile impela.

25. Imvamisa yesethi ye-generator ayizinzile. Yini inkinga enkulu?

Impendulo: Inkinga enkulu ukuthi ijubane lokujikeleza kwe-generator alizinzile.
