La leduri conteaza curentul,tensiunea de functionare e o constanta pt fiecare tip de led (IR,UV,rosu,albastru,verde,galben,portocaliu).Ledurile se alimenteaza prin scc pt limitarea curentului la o valoare acceptata de acesta. In anumite conditi rezistenta este o scc.Fa grupuri de 2 leduri serie+rezistenta,grupuri pe care le legi in paralel.Rezulta o legare mixta.
