  • Electric Charge - 605 Words
    In some Greek experiments, objects attracted each other after rubbing. Other experiments produced objects that pushed away, or repelled, each other. The evidence showed that electric force made matter either attract or repel other matter. Electric force is caused by electric charge. Electric charge is a property of the bits of matter within atoms. Electric force can cause matter to attract or repel because there are two kinds of charge – positive and negative charge. The effects of...

    ELECTRICITY I. DISCOVER OF ELECTRICITY About 600 B.C., Thales, a Greek philosopher and scientist, observed that a piece of amber attracted small bits of “paper” or very thin wood shavings after it was rubbed with wool. He had discovered, in effect, static electricity. William Gilbert, an English scientist in the sixteenth century, found that many other different materials could be made to act like amber. Whenever these objects were rubbed against each other, they were able to attract each...

  • Floating Charge - 877 Words
    An issue of distinguishing a fixed and a floating charge has considerable significance particularly for the parties involved in commercial relationships. It follows from the fact that under English law a fixed charge has a priority over a floating charge that means the former will prevail over the latter even though the company has granted a floating charge to the creditor prior to the creation of a fixed security. Another reason is that under the provisions of Insolvency Act 1986 holders of a...

    g A. Ion exchange Chromatography Ion exchange chromatography is a process for separating proteins and other molecules in a solution based on differences in net charge. Ion Exchange Chromatography relies on charge-charge interactions between the proteins in your sample and the charges immobilized on the resin of your choice. Ion exchange chromatography can be subdivided into cation exchange chromatography, in which positively charged ions bind to a negatively charged resin; and anion exchange...

    INTRODUCTION: ELECTROLYSIS Process used: The key process of electrolysis is the interchange of atoms and ions by the removal or addition of electrons from the external circuit. The desired products of electrolysis are often in a different physical state from the electrolyte and can be removed by some physical processes. For example, in the electrolysis of brine to produce hydrogen and chlorine, the products are gaseous. These gaseous products bubble from the electrolyte and are collected 2 NaCl...

    The Electric Field inside a Conductor The nuclei of the atoms of a conducting solid remain almost in their places in the crystal lattice, while the electrons relatively move a lot. In an insulator, the electrons are constrained to stay with their atoms (or molecules), and at most, the charge distribution is displaced slightly. The motion of the electrons due to the external electric field constitutes an electric current. Since the negatively charged electrons are moving to the left, the...

    Electricity is a form of energy. Electricity is the flow of electrons. All matter is made up of atoms, and an atom has a center, called a nucleus. The nucleus contains positively charged particles called protons and uncharged particles called neutrons. The nucleus of an atom is surrounded by negatively charged particles called electrons. The negative charge of an electron is equal to the positive charge of a proton, and the number of electrons in an atom is usually equal to the number of...
