Ukuba ukukhanya okukhokelwayo kunengxaki yokudanyaza, okuninzi kunokwenzeka ukuba kukho ingxaki kumqhubi (isiguquli). Emva koko kufuneka sibuyisele isiguquli esitsha esikhokelweyo.

Ungayikhetha njani isiguquli esifanelekileyo sokukhanya okukhokelwayo?

Kuqala kufuneka sazi amandla ombane kunye nemveliso ezikhoyo kumqhubi omdala.

umzekelo, kumqhubi ongezantsi, umbane wokuphuma ngu-25-42V, imveliso yangoku yi-135mA

Isiguquli esitsha kufuneka sivelise umbane ofanayo kunye nowangoku.
