Xa i-transformers isebenza ngokuhambelana nemilinganiselo eyahlukeneyo yokuguqulwa, ukujikeleza kwangoku kuya kuveliswa, okuya kuchaphazela ukuveliswa kweenguqu. Ukuba ipesenti ye-impedance ye-transformers ayihambelani kwaye i-transformers isebenza ngokufanayo, umthwalo awukwazi ukuhanjiswa ngokuhambelana nomthamo we-transformers, kwaye umphumo wabaguquli uya kuchaphazeleka. Xa amaqela oqhagamshelwano ahluke, i-transformer iya kuba nephutha lesiphaluka esifutshane.
