Mofuta oa sesupa DC ammeter le voltmeter li hlakotsoe hloohong ea mitha. Hlooho ea mitha hangata ke magnetoelectric galvanometer, e lumellang feela hona joale boemo ba micro ampere kapa milliampere hore bo fete. Ka kakaretso, e ka feela lekanya nyane haholo hona joale le gagamalo. Ka ts'ebeliso e sebetsang, e tlameha ho fetoloa ho holisa boholo ba eona ba ho lekanya haeba e tla metha boholo ba hona joale ba motlakase kapa motlakase. Metara e fetotsoeng e lokela ho lekanngoa le metara e tloaelehileng mme boemo ba eona ba ho nepahala bo lokela ho khethoa. Sesebelisoa sena se fana ka lisebelisoa tse felletseng tsa liteko tsa ho fetola ammeter e nyane ho milliammeter kapa voltmeter. Likahare tsa liteko li ruile, mohopolo o hlakile, o tsitsitse ebile oa tšepahala, mme moralo oa sebopeho o utloahala. E ka sebelisoa haholo-holo bakeng sa teko ea katoloso ea fisiks ea baithuti ba sekolo se bohareng kapa teko ea liteko tsa fisiks le koleche.

Mesebetsi

1. Utloisisa sebopeho sa mantlha le ts'ebeliso ea microamp galvanometer;

2. Ithute ho holisa mefuta ea litekanyo tsa galvanometer le ho utloisisa molao-motheo oa ho aha multimeter;

3. Ithute mokhoa oa ho lekanya oa mitara ea motlakase.
