paun nelu Posted August 28, 2012 Author Share Posted August 28, 2012 daca te refery la rezistenta bobinei , da. Quote Link to comment Share on other sites More sharing options...
dan cod Posted August 28, 2012 Share Posted August 28, 2012 NU la rezistenta bobinei ci in paralel cu deflexia V are o rezistenta de 2W de 220 sau 470 de ohmi.Cand aia se arde face dungi imaginea.Trebuie masurata cu un capat dezlipit ca altfel fenteaza rezistenta bobinei.
