تم الإجابة عليه: من الخطر استخدام منصهر كهربائي مكتوب عليه 30 امبير في دائرة كهربائية تحتاج الى كهربائي مقداره 15 امبير فقط لماذا

لأن هذا المنصهر لا يستطيع أن يحد من الزيادة غير المرغوب فيها للتيار الكهربي في الدائرة فنعد زيادة التيار الكهربي عن 27 أمبير لا ينصهر السلك الرفيع المنصهر فتضل الدائرة مغلقة ويستمر مرور التيار الزائد فترتفع درجة حرارة الأسلاك في الدائرة وقد يؤدي إلى حريق.
