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

The Electric Car has a history but is there a future in the UK or will there be a better option? The invention of the first Electric Car was in 1830 but was not perfected until the creation of rechargeable batteries in 1859. By 1912 50 companies were producing 34‚000 electric cars. Once the development of the electric starting motor occurred and the price of fuel was cheap then the electric cars industry vanished. The oil crisis in the 1970’s caused some re-emergence of electric cars but the

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
