  • Space Charge And Electric Field Distribution

    the physical model and numerical procedure of calculating the dynamics of space charge and electric field distribution in cable insulation material under DC voltage. Electric field distribution and formation of space charge The dependency of electric field distribution on time and temperature is obvious in HVDC system. This is due to the resistivity/conductivity dependency on temperature and electric field [1, 44]. It is also clear that the formation of space charge within the insulation material is depended on both temperature and external applied field [15]. Therefore, the dependent conductivity has a great role on space charge and then on field distribution in DC system. Under steady state DC condition the electric…

  • Mixed Protein Solution For Pancreatic Cancer

    The proteins from each solution will then be precipitated by ethanol and suspended in 2-D cell lysis buffer (). Next, the proteins from the healthy volunteers and the sick volunteers will be stained with CyDye Cy3 and Cy5, respectively, and combined into one solution. The resulting solution will then be subjected to 2-dimensional gel electrophoresis. This will be done by transferring the mixed protein solution to isoelectric tube gel (pH 3-10) and subjecting it to a constant electric current…

  • The Four Fundamental Forces

    time, electrostatic charge and forces were unearthed. Charles Augustin de Coulomb performed an experiment showing that an electrical repulsion implements a law that has the same form as the law of gravity. In 1785, Coulomb published a physics paper stating the force between two particles that are charged is proportional inversely to the square of the distance between them. Then Coulomb 's law was created Coulomb is known for his law and being the founder of the theory of electrical action. The…

  • Static Electricity Research Paper

    Electrostatics is a big branch inside of the tree of physics. When studying electrostatics you will learn about electric chargers that do not move. Static electricity is one of the many things that are covered in electrostatics. An object that has accumulated electric charge has static electricity (“Electricity for kids”, 1). The charges are not on the move nor do they flow from one place to another. It is easy to remember that the charges don’t move in static electricity, because static can be…

  • Lightening Research Papers

    Lightening, something that can light up an inky, blue-black night sky in a flash, is one of nature’s most remarkable phenomenon. To the common man, it is impossible that something so deadly, but venomously beautiful, could come from the sky. I have often wondered what causes such a terrifying occurrence, which is why I plan to explain the causes of lightening. Generally produced in thunderstorms, lightening is formed when liquid and ice particles above the freezing level collide. Once the…

  • Principle Of Electrochromism

    can be simply represented by Equation (1), where M+ can be H+, Li+, Na+ or K+ , 0 < x < 1, and e- are denoting electrons.[2] (transparent) WO3 + xM+ + xe- ↔ 2 MxWO3 (deep blue) ------------- Equation (1) An electrochromic system consists of an ion-containing material (electrolyte) that is of close proximity to the electrochromic layer and the transparent layers for the setting up a distributed electric field. Ions are shuttled back and forth within the electrochromic layer when potential…

  • Salt Water Lab Report

    Conductivity of Salt Water/ Salt Water Circuit Introduction to Physics UBT 1- Task #2 19/11/2015 Western Governors University Thiago Predebon Introduction: Saltwater Circuit; Did you know that you can use salt water to make a light bulb shine? It sounds crazy, but it's true! This is because salt water is a good conductor of electricity. Salt molecules are made of sodium ions and chlorine ions. (An ion is an atom that has an electrical charge because it has either gained or lost an…

  • Characteristics Of Intermolecular Forces

    Ion-Dipole The ionic dipole force is the strongest inter molecular force and involves a force between a charged ion and a polar molecule (molecule with a dipole). This force comprises the electrostatic attraction between an ion (full charge) and a neutral molecule that has a dipole leading to a weaker interaction (due to the partial charge on the polar compound); the positive ion (cation) attracts the partially charged negative end of the a neutral polar molecule and a negative ion (anion)…

  • Essay On Importance Of Water

    digestive system and become water-soluble. This means the dissolved materials can be transported around the body by water in the form of solutions. These nutrients can then pass through the capillaries within the intestinal walls to the blood around the body as they are dissolved in the water. The valuable nutrients can be distributed to the body. Without water, the chemical reactions nutrients such as proteins and carbohydrates would not be absorbable and usable by the body. These nutrients…

  • Electrolytic Synthesis Lab Report

    In the 1800s, chemist Michael Faraday discovered that water could be decomposed in an electrolytic solution into its elements. This discovery was made through the use of an electric current in a process now known as electrolysis. This was the first systematic study of electrolytic solutions (Lower, n.d.). Faraday observed that two requirements must be met in order for a sample of matter to be an electrical conductor. The first requirement is that the sample must contain electrically charged…
