Hi Kamal. Thanks for going through the video. We can surely provide equal power to both the plates. We just need to regulate the voltage and current to individual plate. In that scenario, temperatures of both plates will not be equal and we will not be able to compare their emissivity, because, by basic concept, emissivity can be compared only at same temperature. If same power is provided, temperature of black plate will be less because of higher emission from it to atmosphere. At the same time, temperature of white/polished plate will be higher because of lesser radiation given to atmosphere from it. This physical understanding shall also be helpful in Oral/Viva/Practical examination to the students. All the best with your learning.
شكرا على جهدك....لكن اشعر ان مقاطع الفيديو تميل نحو الناحية الأكاديمية والدراسة الجامعية...ما يهم الانسان غي طلاب الجامعة كيف يحسب تفير في فاتورة الطاقة لمنزل بإضافة طبقات من العزل الحراري ....هذا ما اود معرفته...وشكرا مرة أخرى
