  • 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…

  • Electric Fish Essay

    Many people may ask the question: why study such an exotic sensory system such as the electrosensation in electric fish? Could it be because of the natural curiosity that we as human’s exhibit, or maybe because we are intrigued by the various morphological and physiological adaptations that are seen across a plethora of environments? Well, more evolved organisms have achieved their higher traits not from new mechanisms that spontaneously appeared, but from old mechanisms that they share with…

  • Case Study: Electrochemical Performance Of Li1

    3.4. Electrochemical performance of Li1.2Ni0.13Co0.13Mn0.54O2 3.4.1. Electrochemical charge/discharge behavior Figure 9 (a-d) shows the charge/discharge profiles of four Li1.2Ni0.13Co0.13Mn0.54O2 electrodes (EV, CA/EDTA, CA and EDTA) cycled at 0.1C between 2.0 and 4.8 V, while Fig. 9(e) depicts the initial charge/discharge profiles of four Li1.2Ni0.13Co0.13Mn0.54O2 electrodes under the same conditions. All the initial charge/discharge profiles show the same general features. All the initial…

  • Polarization In Antenna

    Polarization in Antenna Polarization is the basic thing used in transmission antennas for the propagation and reception of the signals. As we know that antenna emits electromagnetic waves in the space for the communication purposes. These two types of waves as depicted by the name Electro-Magnetic is a combination of electrical and magnetics fields. These two waves are mutually orthogonal i.e. oriented at an angle of 90o with each other. The general wave form is given as Fig: Electromagnetic…

  • Dipole-Dipole Array Analysis

    Dipole-dipole array has wide using in resistivity/I.P. surveys because of the low E.M. coupling between the current and potential circuits. The arrangement of the electrodes is shown in Figure( )., Electrodes c1 and c2 are separated by a distance (a), and electrodes p1 and p2 are separated by a distance (b). the distance between the potential electrodes pair c1-c2 is the same as the distance between the potential electrodes pair P1-P2 and the distance between the centers of the respective…

  • Copper Wire And Resistivity Essay

    Introduction: In the following experiment, I am going to test whether the copper wire will have less Resistivity (ρ) than the iron wire, and/or the two copper wires connected together. Resistivity is defined as how strongly a particular material resists current, and is measured in Ohm-meters (Ω-m). Electrical resistance (R) is the opposite of the flow of electrons, or the passage of an electrical current. Electrical conductivity (σ) is the opposite of resistivity and is measured in Siemens…

  • Magnetic Field Therapy Research Paper

    Magnetic Field Therapy Danielle Scott Vermont Technical College Magnetic Field Therapy Magnetic field therapy should be used as a complementary and alternative medicine before pharmaceutical interventions to treat patients. Magnetic field therapy penetrates the entire body and has fewer side effects. Magnetic field therapy has many benefits to offer patients to maintain health and treat illness. Magnetic field therapy provides a non invasive, safe, and easy method. The physiological…

  • The Atomic Model

    In order to understand the composition of stars, we look at the spectral lines of the atoms outside the star. From the lines in the spectrograph, we are able to find out how much of each and what kind of atoms there are in the stars. Through electromagnetism, quantum mechanics, and the atomic model, we are able to see that stars are made primarily…

  • The Philadelphia Experiment Conspiracy Theory

    detailed evidence or documents. The Philadelphia experiment conspiracy theory is a worldwide experiment that took place during World War II when the government used Albert Einstein’s unified field theory to attempt teleportation using gravity and electromagnetism, but considering the fact that most crew members suffered and died because the forces used it was labeled the world’s first…

  • Carl Friedrich Gauss And The CGS Framework

    unit of length, the gram as the unit of mass, and the second as the unit of time. All CGS mechanical units are unambiguously gotten from these three base units, however there are a few distinctive methods for extending the CGS framework to cover electromagnetism. The CGS framework has been to a great extent supplanted by the MKS framework…
