  • 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…

  • Lithium And Electrons

    Lithium is the chemical element of atomic number 3, a soft silver-white metal. It is the lightest of the alkali metals. The two main parts of every atom are neutrons and protons. The three main subatomic particles that form an atom are protons, neutrons, and electrons. Electrons are the smallest of the three particles that make up atoms. Electrons are found in shells or orbitals that surround the nucleus of an atom. Protons and neutrons are found in the nucleus. They group together in the center…

  • 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…

  • 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…

  • 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…

  • 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…

  • What Effect Would This Have On Earth's Climate

    bulb when more and more bulbs are connected in parallel? Based on your answers above, what are the rules for current and voltage for a series circuit and for a parallel circuit?” For the series circuit the amount of voltage is divided equally between all the bulbs, so adding more will result in them being less bright. In this type of circuit the electric current travels through a single path through the circuit, the voltage of the device being used is proportional to the resistance, the…

  • 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…

  • Early Atomic Experiment Research Paper

    electrical charge. This leads him into his next action, JJ Thomson was able to construct another scientific system to help him discover the electron. This system was very similar except instead the glass tube would be in a bulb type shape, one end would expand outwards like a fat bulb while the other side stays the original cylindrical tube shape. This time JJ would place the anode quite close to the cathode, and yet again they would be hooked up to a high voltage power source. The Cathode ray…
