first applications of electricity was the first incandescent light bulb in around 1870. The electric overhaul of society obviously brought many fresh new dangers with it‚ but it eliminated some of the old ones‚ like the naked flames of gas lighting that was commonly used in homes and factories then. The Joule heating effect that can be found in light bulbs is also present in electric heating. Electric heating has been thought of as wasteful in the past because in order to create that heat energy

I. Physical Features Electric eels are not really eels‚ they are actually ostariophysians‚ but have a strong physical resemblance to true eels. . An electric eel is mostly tail. The internal organs are compressed into the anterior (front) 1/5th of the body‚ and the rest of the fish consists of the long‚ electricity-producing tail. The tail contains the electric organs: Sachs’ organ‚ Hunter’s organ‚ and main organ. Extending down the entire tail region is an elongated anal fin. There are no dorsal

All types of Motor & Generators - AC & DC‚ Starters:Induction Motor (3 Phase):The production of a rotating magnetic field (RMF) is essential for the operation of alternating current (a.c.) induction motors. The speed of rotation of an RMF is known as the synchronous speed and this will be governed by the value of the supply frequency and the number of poles wound within each phase winding. Each of the phase windings are 120 electrical degrees apart. Synchronous speed can be calculated using the following

pushed away‚ or repelled‚ each other. The evidence showed that electric force made matter either attract or repel other matter. Electric force is caused by electric charge. Electric charge is a property of the bits of matter within atoms. Electric force can cause matter to attract or repel because there are two kinds of charge – positive and negative charge. The effects of electric force can be summarized as the law of electric charge: Pieces of matter with the same kind of charge repel
