Berthama perbehet prej nje numri te madh te fletezave te holla prej hekuri dhe te izoluara ndermjet vete.Bobina qe lidhet me burimin e rrymes quhet primare.kurse bobina prej se ciles del rryma quhet sekondre
Transformatoret
Vegla qe sherben per zvogelimin ose zmadhimin e tensionit ose te rrymes quhet TRANSFORMATOR (qe nga gjuha latine transformatere do te thote te ndërrosh ose shnderrim
Transformatori paraqet nje berthame te hekurit ne forme te katerkendeshit me dy bobina prej perquesve te izoluar dhe te vendosur ne dy anet e kunderta te berthames se hekurit
Kur bobina e pare lidhet ne qarkun me rryme alternative me tension U1, ne te shfaqet fusha magnetike e cila me veprimin e saj indukon tension alternativ U2 ne bobine sekondare.
Zbatimi
Transformatoret kane zbatim te madh ne praktike p.sh ne zilen elektrike,radio dhe stacione televizive,ne aparate te ndryshme te amviserise etj.Me rendesi te veqante eshte zbatimi i tyre ne bartjen e energjise elektrike ne largesi te medha prej centralit ku prodhohet rryma deri te shpenzuesi.
