Lits'ebetsong tsa indasteri, mehlala ea puisano kapa mehlala ea AC e bapala karolo ea bohlokoa ho utloisisa le ho ntlafatsa lisebelisoa tsa motlakase. Mefuta ena e bohlokoa bakeng sa ho sekaseka boits'oaro ba li-circuits tsa AC, tse sebelisoang haholo liindastering tse fapaneng ka lebaka la ts'ebetso ea tsona ea phetisetso ea matla le ho feto-fetoha ha lits'ebetso.

Mefuta ea puisano ea indasteri e kenyelletsa letoto la meralo ea theory le e sebetsang e thusang baenjiniere le litsebi ho rala, ho etsisa le ho rarolla mathata a litsamaiso tsa motlakase. Li bohlokoa haholo libakeng tse kang tlhahiso, likhokahano le matla, moo matla a tšepahalang le ts'ebetso ea sistimi e leng bohlokoa.

Bohareng ba mofuta oa indasteri ea AC ke mohopolo oa sinusoidal waveform, e emelang thepa e fapanyetsanoang ea hona joale. Mefuta ena e sebelisa li-equation tsa lipalo ho hlalosa kamano e teng lipakeng tsa voltage le hona joale potolohong, ho nahanoa ka lintlha tse kang impedance, phase angle le frequency. Ka ho sebelisa mehlala ena, litsebi li ka bolela esale pele hore na likarolo tsa motlakase li tla itšoara joang tlas'a maemo a fapaneng, ho ba lumella ho etsa liqeto tse nang le tsebo mabapi le moralo le ts'ebetso ea tsamaiso.

Ho feta moo, mefuta ea likhokahano tsa indasteri e kenya letsoho ntlafatsong ea mahlale a tsoetseng pele joalo ka marang-rang a bohlale le litsamaiso tsa matla a ka nchafatsoang. Ba thusa ho kopanya mehloli e fapaneng ea matla le ho netefatsa hore kabo ea motlakase e lula e tsitsitse ebile e sebetsa hantle. Ha indasteri e ntse e tsoela pele ho fetoha, bohlokoa ba ho etsa mohlala o nepahetseng oa AC bo ntse bo bonahala haholoanyane, bo tsamaisang boqapi le ho ntlafatsa ts'ebetso ea ts'ebetso.

Ka kakaretso, mokhoa oa puisano oa indasteri ke sesebelisoa sa mantlha sa tlhahlobo le taolo e sebetsang ea litsamaiso tsa motlakase ho pholletsa le mafapha. Ka ho sebelisa mefuta ena, litsebi li ka ntlafatsa ts'ebetso, tsa fokotsa litšenyehelo, le ho netefatsa ts'epahalo ea sistimi ea motlakase, 'me qetellong li kenya letsoho ntlafatsong ea mahlale a indasteri.
