  • Thomas Alva Edison's Accomplishments

    Thomas Alva Edison possessed a tremendous amount of skills as an inventor and dedicated a great amount of time and efforts in his laboratory. Edison realized at a young age that creating and inventing intrigued him. He drafted a great amount of notebooks containing sketches, ideas, and explanations for his inventions. His ambitions and aspirations led Edison to own many companies and accumulate over 1,000 patents for his inventions. As an inventor, Thomas grew up with a mindset that he would…

  • The Properties Of Dielectric Materials

    1.1 Dielectric Materials Dielectric materials are insulating materials that exhibit the property of electrical polarization. Dielectric materials support charge by acquiring a polarisation in an electric field. 1.1.1 Electric susceptibility and permittivity When a capacitor with capacitance C0 is filled with a dielectric material, its charge storage capacity (capacitance) increases to a value of C. Than susceptibility (χ^') of the dielectric materials is given by χ^'= (C-C_0)/C Dielectric…

  • Statement Of Purpose In Electronic Engineering

    I am a student of electrical and electronic Engineering and I like taking up my further studies with an outlook of innovative research. I frame my goals in that direction and put up the hard work to realize them as I strongly believe that the hard work is the key to success. I have a strong feeling that whatever the goals I have and whatever the strong frame work I prepare, the set goals may not be realized unless there is congenial academic environment and also an efficient academic agency to…

  • Samuel Morse's Use Of The Dots And Dashes In The Telegraphs

    Once he returned home he began drawing the plans for his electrical telegraph. His first model was composed of a wooden frame, which would hold an electromagnet, paper, and a marking pencil suspended from a pendulum. The pencil would mark on the paper as the electric circuit was opened and closed. What is now known today as Morse code is what Samuel Morse created when he used dots and dashes in his telegraph. To continue his experiments and research he needed financial support. Fortunately,…

  • Resistivity In Wire

    resistance to water flow than does an unplugged hose. If we want to get more water out of the hose, we would need to turn up the water pressure at the hydrant. The same is true with electricity. Materials with low resistance let electricity flow easily. Materials with higher resistance require more voltage (EMF) to make the electricity flow. The scientific definition of one ohm is the amount of electrical resistance that exists in an electrical circuit when one amp of current is flowing with…

  • Magnetic Propulsion Essay

    Magnetic propulsion Magnetic propulsion refers the use magnetic energy to move objects from one point to another. Due to increased demand for clean energy, the use of electromagnetic propulsion will also be a new way of powering the future vehicles. This method employs the use of electrical current to create an opposing magnetic field that results in repulsion. The electromagnetic propulsion has been in use in motors to create a rotational force which drives the vehicles wheel forward. However…

  • Electricity Vs Wind Energy Essay

    Today there are many debates on what we, Humankind, should do about our environmental problems such as pollution, trash disposal, recycling, saving trees, .etc. People have been trying to find more cost effective and efficient mean of producing electricity instead of the use of fossil fuels that hurt the environment and wildlife around us. Each year about 1.7 billion pounds of pollution are pumped into the air a day by coal plants alone, which is quite a lot. But what about Eco-friendly methods…
