Mudunhu reAC, kune mhando mbiri dzesimba remagetsi rinopihwa kumutoro kubva kumagetsi: rimwe isimba rinoita basa uye rimwe isimba rinoita basa. Kana mutoro uri simba rinoita basa, simba rinoshandiswa isimba rinoita basa, kana mutoro uri simba rinoita basa kana kuti rinoita basa, simba rinoita basa isimba rinoita basa. Voltage yesimba rinoita basa uye simba rinoita basa muchikamu chimwe chete (simba reAC musiyano uripo pakati pesimba rinoita basa nerinoita basa), kana voltage ikadarika simba rinoita basa, isimba rinoita basa rinoita basa; kana simba rinoita basa rakapfuura simba rinoita basa, isimba rinoita basa rinoita basa.

Simba rinoshanda isimba remagetsi rinodiwa kuti michina yemagetsi ishande zvakanaka, kureva kuti, kushandurwa kwesimba remagetsi kuita mamwe marudzi esimba (simba remakanika, simba rechiedza, kupisa) remagetsi. Semuenzaniso: 5.5 kilowatts yemota yemagetsi ndiyo 5.5 kilowatts yesimba remagetsi inoshandurwa kuita simba remakanika, ichifambisa pombi kuenda kupombi yemvura kana muchina wekupura; michina yakasiyana-siyana yemwenje ichashandurwa kuita simba rechiedza, kuti vanhu vagare uye vashande nemwenje.

Simba rinoita basa harina kunyatsojeka; ndiro simba remagetsi rinoshandiswa pakuchinjana magetsi nemagineti mukati medunhu uye kusimbisa nekuchengetedza simba remagineti mumidziyo yemagetsi. Harishande kunze, asi rinoshandurwa kuita mamwe marudzi esimba. Chero mudziyo wemagetsi une coil yemagetsi unoshandisa simba rinoita basa kuti ugadzire simba remagineti. Semuenzaniso, rambi re fluorescent re 40-watt rinoda anopfuura ma watts makumi mana esimba rinoita basa (ballast inodawo kushandisa chikamu chesimba rinoita basa) kuti ibudise chiedza, asi rinodawo simba rinoita basa re 80 kuti ballast coil igadzire simba remagineti rinochinjana. Nekuti hariite basa rekunze, asi rinongonzi "reactive".
