Fluorescent tube lamp (FTL), in very simple words, produces light from excitation of atoms due to bombardments of electrons. A compact fluorescent lamp (CFL) is a coiled-shaped version of FTL. http://upload.wikimedia.org/wikipedia/commons/3/31/06_Spiral_CFL_Bulb_2010-03-08_(white_back).jpg...

Thanks bandersnatch, that clear things a lot. But still I have a little bit more to ask. This is the complete paragraph from one of the textbooks I read: One of the end-of-chapter exercises also stress again on that the conversion "loss of GPE of water ==> gain in KE of water (or turbine...

Thanks Drakkith. Just to clear things up, the energy conversion is (when turbine starting up) GPE of water ==> KE of water ==> KE of turbine ==> electrical energy (when turbine running at steady speed) GPE of water ==> KE of water ==> work done against electromagnetic force ==> electrical...

(this is the first time I post. hope this is in the correct board) So I want to know about how the internal energy of water has been converted into electrical energy when the turbine is rotating at a steady speed. I have read several textbooks and they all give me several answers: 1. GPE of...
