Can friction power a light bulb
WebIn a simple circuit such as a light bulb with a voltage applied to it, the resistance determines the current by Ohm’s law, so we can see that current as well as voltage must determine the power. Figure 19.20 On the left is a 25-W light bulb, and on the right is a 60-W light bulb. WebIn this list Hendricks (1959) includes also responses of parts of plants not exposed to light which can only be affected by photo-induced regula- tors: bulb formation, rhizome production and root development. The preceding analyses serve only to suggest the extraordinary range of photoresponses which the ecologist must consider.
