Electricity is a necessity in our life. Many people cannot function on a daily basis without it. Everything in a house runs mostly on electricity. Great precision and a lot of work are needed around the clock to ensure that energy is available for use. The process of producing electricity is taken for granted by most people because it always seems to be readily available. No one truly appreciates the need for electricity until the power goes out. Many years ago, food was kept cool in ice chests, homes were kept warm using wood-burning ovens, and were lit using kerosene lamps. Thanks to the development of electricity, technological advances have evolved. Without electricity, it would be difficult to produce the voltage and amperage needed to produce high-quality x-rays. Although electricity may be the main contributor to the production of X-rays, transformers and rectifiers are also of great importance. Electricity has paved the way for advances in the medical field. The production of electricity All matter is made up of atoms, which in turn are made up of even smaller subatomic particles. These subatomic particles are called protons, neutrons and electrons. The electrons orbit around the nucleus which is made up of protons and neutrons. If enough energy is added to an electron, it will move from its orbit and move into the next level. Valence electrons don't have a shell to go into, so they will jump to another atom. Electrons flow and move in certain materials known as conductors. Protons are unable to do this because they are heavier than electrons. Conductors include aluminum, silver, copper, and gold. Copper is used mainly for its conductive capabilities and because it is present in large quantities ( Killinger & Killinger, 2003)....... half of the paper ......and if the current was alternating ( Bushong, 2008). Transformers are needed to provide a high voltage to the anode portion of the X-ray tube. Power is only available at 110 or 220 volts. The voltage required for the X-ray tube is kilovolts. The two types of transformers used in X-ray production are step-up and step-down transformers. (NDT Resource Center). References Bushong, S. C. (2008).
