Wareegga AC-ga, waxaa jira laba nooc oo koronto ah oo laga helo culayska korontada: mid waa awood firfircoon kan kalena waa awood falcelis ah. Marka culaysku yahay culays iska caabin ah, awoodda la isticmaalo waa awood firfircoon, marka culaysku yahay culays awood leh ama mid soo jiidasho leh, isticmaalku waa awood falcelis ah. Danabka awoodda firfircoon iyo hadda isla marxaladdaas (awoodda AC waa farqiga u dhexeeya awoodda firfircoon iyo tan falceliska ah), marka danabku ka badan yahay hadda, waa awood falcelis ah oo soo noqnoqota; marka hadda uu ka badan yahay danabka, waa awood falcelis ah oo soo jiidasho leh.

Awoodda firfircooni waa awoodda korontada ee loo baahan yahay si loo ilaaliyo shaqada caadiga ah ee qalabka korontada, taas oo ah, beddelka tamarta korontada ee noocyada kale ee tamarta (tamarta farsamada, tamarta iftiinka, kulaylka) ee awoodda korontada. Tusaale ahaan: 5.5 kiilowatts oo matoor koronto ah waa 5.5 kiilowatts oo tamar koronto ah ayaa loo beddelaa tamar farsamo, taasoo bamka ku kaxaysa inuu biyaha bamgareeyo ama mashiinka wax lagu tunto; qalabka kala duwan ee nalalka ayaa loo beddeli doonaa tamar iftiin ah, si dadku u noolaadaan oo ay u shaqeeyaan nalalka.

Awoodda fal-celinta waa mid aan la taaban karin; waa awoodda korontada ee loo isticmaalo is-weydaarsiga goobaha korontada iyo birlabta ee wareegga iyo in la dhiso oo la ilaaliyo goobta birlabta ee qalabka korontada. Ma shaqeyso dibadda, laakiin waxaa loo beddelaa noocyo kale oo tamar ah. Qalab kasta oo koronto oo leh gariirad elektromagnetic ah wuxuu isticmaalaa awood fal-celin ah si uu u dhiso goob birlab ah. Tusaale ahaan, laambad iftiin leh oo 40-watt ah waxay u baahan tahay in ka badan 40 watts oo awood firfircoon ah (ballastku sidoo kale wuxuu u baahan yahay inuu isticmaalo qayb ka mid ah awoodda firfircoon) si uu u soo saaro iftiin, laakiin sidoo kale wuxuu u baahan yahay qiyaastii 80 awood fal-celin ah si gariiradda ballast-ka ay u dhisto goob birlab ah oo beddelan. Sababtoo ah ma qabato shaqo dibadeed, kaliya waxaa loogu yeeraa "fal-celin".
