Electricity has become the main sources of domestic energy in Australia over the last 200 years and played an important role in today’s society‚ industry . In the early time when the British started to settle in Australia‚ firewood was the most important fuel. In 1831‚ Michael Faraday put forward the electromagnetic induction‚ which led to the development of electric generators and made the large amount of electricity supply become possible. After 1879 when the perfect light globe was designed

Ways to save electricity Nowadays many people have electricity‚ but they don’t know how to use it wisely. There is many way to save electricity. We must use electricity wisely. 1. Way is only use electricity when needed. 2. Replace all of your inefficient incandescent light bulbs with energy efficient CFL bulbs. Replace halogen spotlights with much more efficient and longer lasting LED Spotlight. 3. Hang your clothes out to dry rather than using an electric tumble dryer. Ideally use a spin dryer before

The overuse of electricity affects the ecosystem in several ways. The overuse of electricity can lead to an increased carbon footprint‚ increased climate change‚ reduction in supply‚ and high energy costs. The abiotic factors that contribute are electricity‚ smoke‚ temperature‚ climate‚ and mining. The biotic factor that affects it is people. Leaving your laptop plugged in all the time will use up 300 kilowatts an hour each year. A natural consequence of overusing energy is increased costs for you

Hazards of Static Electricity; Lightning Lightning is a massive electrostatic discharge between the electrically charged regions within clouds or between a cloud and the surface of a planet. It is the sudden high-current discharge caused by the atmosphere’s electrical breakdown. Lightning is also one of the most deadly natural phenomena known to man. Lightning is an electric current; thus within a thundercloud up in the sky‚ many small bits of ice (frozen raindrops) collide into each other as

150 years ago‚ approximately around 1886‚ electricity was becoming a very exciting thing as AC plants started to appear all over the world. This meant great change for not only our establishments but also‚ for families that were near it and could afford it. It was the dawn of aluminum‚ cars and now a better way of life with electricity‚ life was about to get more exciting as well as easier for many families. Around the time of the late 1800’s‚ under the idea of “separate spheres”‚ caring for children

Electricity is the set of physical phenomena associated with the presence and flow of electric charge. Electricity gives a wide variety of well- know effects such as lightning‚ static electricity‚ electro magnetic induction and the flow of electrical current. In addition‚ electricity permits the creation and reception of electromagnetic radiation such as radio waves. Electrical phenomena have been studied since antiquity‚ though advances in the science were not made until the seventeenth and eighteenth

Atomic Structure & Electricity 1. Draw an atom with an atomic number of 12. Label the protons‚ neutrons‚ and electrons. Use the periodic table to identify which atom you have drawn. 2. How many valence electrons are present in this atom? 2 3. Would this atom prefer to gain or lose electrons? Why? Lose‚ because the octet rule dictates that if there is less than 4 valance electrons‚ they would prefer to leave the atom. 4. Describe the differences between conductors‚ semiconductors
