白炽电灯就是普通的照明灯泡,主要由灯丝和玻璃泡组成.它虽然结构简单,却应用了很多物理学知识. 白炽电灯的工作原理是应用电流的热效应,灯丝通电发热,达到很高的温度,以至炽热发光.从能的转化角度来看,白炽电灯工作是将电能转化为灯丝的内能和光能. 对于一个白 Incandescent lamps are ordinary lighting bulbs, mainly composed of filaments and glass bubbles. Although it has a simple structure, it uses a lot of physics knowledge. The working principle of incandescent lamps is the thermal effect of the application of electricity, the filaments are energized and heated to reach a very high temperature. As far as the glow glows, from the point of view of energy conversion, the incandescent lamp works by converting electrical energy into the internal energy and light energy of the filament.
