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

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

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
