  1. Buna ziua. Am observat ca daca introduc un transformator toroidal intr-o carcasa de sursa de PC si conectez o sarcina in secundarul transformatorului cutia incepe sa vibreze destul de puternic, iar daca strang cu mainile de cutie, atunci vibratiile se atenueaza. Transformatorul a fost fixat, pe o bucata de cablaj, cu sistemul clasic format din 2 bucati de cauciuc si un disc metalic, iar cablajul a fost fixat cu suruburi in interiorul cutiei de la sursa de PC. Daca pun acelasi transformator toroidal pe masa si conectez acelasi consumator in secundarul transformatorului, acesta scoate un sunet foarte slab, perceptibil doar cu urechea lipita de transformator. Ce se poate face pentru a anula (sau macar atenua) vibratiile cutiei de sursa de la PC ?
