在初三电学部分内容当中,灯泡类问题最为常见,题型种类也较多,其中判断灯泡亮暗类问题较为突出,部分同学在解题时容易出错.下面就一道电学类判断题加以适当变换,对灯泡在不同情况下的亮暗情况加以判断.原题有两只灯泡A和B,规格分别为“6 V,6 W”和“12 V,6 W”.甲同学认为A、B两只灯泡额定功率相同,它们在发光时的亮暗程度应相同;乙认为尽管A、B灯泡的额定功率相同,
In the third part of the electrical content, light bulbs are the most common problems, and there are many types of questions, among which light bulbs are more prominent. Some students are prone to make mistakes in solving problems. The following is an appropriate transformation of a class of electrical judgment questions to determine the light and dark conditions of the bulb under different conditions. There are two bulbs A and B in the original title with specifications of “6 V, 6 W” and “12 V, 6 W”. A classmate thinks that the two bulbs A and B have the same rated power, they should have the same lightness and darkness when they emit light, and B think that although the rated power of the A and B bulbs are the same,
