1. ukusebenza mihla le, musa ukuchukumisa ngokuthe ngqo nezandla, ngakumbi kukho amanzi, ioyile, kunye nolunye ulwelo.
2. gcina udonga lwe-tube lucoceke, ngakumbi {uthuli {1} . kuba le nto ithembisa i-radiaviolet .
3. xa umatshini uyeka ukuprinta kwaye akasetyenziswanga ixesha elide, ifilimu yefilimu yothuli inokuvela kumphezulu wesibane ukunqanda uthuli kunye.
4. vula isibane esikhokelweyo ikhava iinyanga ezintathu, ukusula kwaye ucoce imigca, ngaphakathi, kwaye uphephe ukuqokelela kwe-inki okanye {2}.
5. Iiparameter ze-transformer kufuneka zihambelane neeparamitha zesibane, i-voltage kunye ne-fultage kwaye okwangoku aziyi kudlula kwisalathiso soyilo .
6. yesayensi kunye nokufihlakeleyo
