1 Chapter I THE PROBLEM AND ITS BACKGROUND Introduction Electricity is found all around the world–powering technology like cell phones, computers, lights, soldering irons, and air conditioners. It’s tough to escape it in the modern world. Even when you try to escape electricity, it’s still at work throughout nature, from the lightning in a thunderstorm to the synapses inside our body. From the factories using electricity and to the gadgets used today, it is no doubt that electricity has almost become a necessity. (Jimbo, 2015) Electricity is commonly produced using two types of energy, renewable and non – renewable energy. Non - renewable energy comes from sources that will run out or will not be replenished in our lifetimes. Most non-renewable energy sources are fossil fuels: coal, petroleum, and natural gas. (Boyle, 2012) Renewable energy is energy that comes from resources, which are naturally replenished, on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat. ( Sørensen , 2010) Electricity is commonly produced using an Electric Generator. An Electric Generator is a device that converts mechanical energy to electrical energy by applying the principle of Electromagnetic Induction. Michael Faraday’s Law of Electromagnetic Induction states that a voltage is induced in a circuit whenever relative motion exists between a conductor and a magnetic field. Electric Generators work under this concept. 1

2 By adding a turbine to these generators, kinetic energy is transformed to electrical energy. (Richardson, 2006) An Engine is a machine with moving parts that converts power into motion. It converts one form of energy, such as heat, into mechanical energy. Engines are commonly used in automotive to run them. They are usually run from fuels such as gasoline, diesel, and heat. In other cases, engines are also used in conjunction with generators to produce electrical energy. For example, a diesel engine can be combined with an electric generator to provide a substantial amount of electrical energy. Other practical uses, such as water pumps, may also be incorporated with engines. (Jensen, 2013) Temperature is a measure of the ability of a substance, or more generally of any physical system, to transfer heat to another physical system. The higher the temperature of an object is, the greater the tendency of that object to transfer heat. Heat energy flows from warmer to cooler places or objects. In air, cooler air tends to sink due to less kinetic

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
