    Cable Sizing and Selection Introduction: One of the important aspects of designing any electrical system is to select an appropriate type and size of a cable. Too much small size of cable generates a lot of heat in a cable which will caused permanent damage to an insulation of a cable and using a too much large cable size means we are wasting our money on copper because copper is the costly material for cables. So we must have to select a cable that is neither of too small nor too large size

    CHAPTER ONE Introduction The application of physical principles for detecting inhomogenities in materials without impairing the usefulness of the materials has brought into being a technique known as “Non-Destructive Testing” (NDT). Every day more and more is being demanded of materials because materials are being subjected to service and environmental conditions never before encountered. If this field of technology is to fulfil and achieve its full potential, not only more but also better NDT must

    Superconductors research task What is a super conductor? A superconductor is an element or metallic alloy which when cooled below a certain temperature the material loses all electrical resistance. Therefore superconductors can allow electric current to flow without any energy loss due to no resistance. This type of current is also known as supercurrent. Due to the material has lost its electrical resistance the superconductor can carry a current indefinitely without losing energy. One properties

    The first transistor was demonstrated on Dec. 23, 1947, at Bell Labs by William Shockley. This new invention consisting of P type and N type semiconductive materials (in this case germanium) has completely revolutionized electronics. Transistors quickly replaced vacuum tubes in almost all applications (most notably those in discrete logic). Today when we think of transistors the first thing that comes to mind is computers. Advances in transistor technology and manufacturing processes as well as

    I. Introduction In today’s society, the need to have an adequate supply of electricity to run everyday tasks is in greater demand than ever. Everyday we turn our lights in our homes on and off without really thinking about if there is enough electricity to power each and every light. Throughout this paper, we examine Kirchhoff’s Voltage Law the sum of the electrical potential differences around any closed network is zero [1]. Represented by the equation ΣV=0, which means v1+ v2+ v3+…+ vn=0 [2].

    Chlorine is a greenish yellow gas which combines directly with nearly all elements. Chlorine is a respiratory irritant. The gas irritates the mucous membranes and the liquid burns the skin. As little as 3.5 ppm can be detected as an odour, and 1000 ppm is likely to be fatal after a few deep breaths. It was used as a war gas in 1915. It is not found in a free state in nature, but is found commonly as NaCl (solid or seawater). Table: basic information about and classifications of chlorine. • Name:

    the temperature was higher for that measurement. Whilst unlikely (due to the two sets of results), this would cause a higher resistance as explained previously. However, it is now known, after researching the metal alloy “constantan,” that the resistivity (the electrical resistance of a conductor of particular area and length) of this alloy is not affected by temperature. Therefore, in these experiments Ohm’s Law does not apply.

    Resistance of a Wire Experiment Task To investigate how the resistance of a wire is affected by the length of the wire. Theory What is resistance? Electricity is conducted through a conductor, in this case wire, by means of free electrons. The number of free electrons depends on the material and more free electrons means a better conductor, i.e. it has less resistance. For example, gold has more free electrons than iron and, as a result, it is a better conductor. The free electrons
