مبدأ عمل المصباح الكهربائي (Info)
يعمل المصباح الكهربائي التقليدي على مبدأ التوهج؛ بحيث يحتوي المصباح على موصل معدني رقيق وقصير ما بين قطبين كهربائيين، وبالتالي يملك مقاومة كهربائيّ عالية تعمل على ارتفاع درجة حرارته بشكل كبير ثمّ التوهج عند مرور التيار الكهربائي من خلاله، وبالتالي توليد ذلك الضوء المرئي.
