Sawa blessed, hebu tueleze jinsi seli inavyofanya kazi.

Wakati swichi imefungwa, seli huunda tofauti ya uwezo (potential difference) au voltage katika mzunguko. Tofauti hii ya uwezo huunda uwanja wa umeme (electric field) ndani ya waya. Uwanja huu wa umeme husukuma elektroni huru katika waya, na kuzifanya zitiririke kutoka ncha hasi ya seli kuelekea ncha chanya. Mtiririko huu wa elektroni ndio tunaita mkondo wa umeme (electric current), na mkondo huu unapopita kwenye balbu, huifanya iwake.
