What can you say about the quote? 2. Do you think this quote is true or not? Why? Why not? 3. How do you relate this quote to our daily lives? 4. Base on the quote above is there any grey side of electricity What is It ELECTRICITY’S CHARACTERISTICS Electricity is one of the human major needs that basically supplies and serves as the blood of our domestic appliances and gadgets as well as in the industries. Electricity is a natural phenomenon that occurs throughout nature and takes many different forms. Basically electricity is simply defined as the flow of electric charge, but it is not as simple as that for there are lying questions needed to be answered like: How do we move them? Where do the charges come from? How do they power our appliances? How do they react to the loads? And many more things we need to know about the electricity.
- 7. THE ATOM Generally, wecan say that an atom is the smallest constituent unit of ordinary matter that constitutes a chemical element. Meaning almost everything that you can see is made up of atoms. Yes, even the electricity is relying to atoms for it to move, propagate and consume. An atom is built with a combination of three distinct particles: electrons, protons, and neutrons. Protons and neutrons are in the center of an atom however the electron is orbiting around the two. Fig. 1 An Atom Model Charges of an Atom: Electrons – Negatively Charged Protons - Positively Charged Neutrons – No Net Charge Every atom must have at least one proton in it. The number of protons in an atom is important, because it defines what chemical element the atom represents. For example, an atom with just one proton is hydrogen, an atom with 29 protons is copper, and an atom with 94 protons is plutonium. This count of protons is called the atom's atomic number. On the other hand, the proton's nucleus-partner, neutrons, serve an important purpose; they keep the protons in the nucleus and determine the isotope of an atom. However the neutron is not really part of the spotlight in this lesson. Lastly, the electrons are vital to the workings of. In its most stable, balanced state, an atom will have the same number of electrons as protons. As in the Bohr atom model, a nucleus with 29 protons (making it a copper atom) is surrounded by an equal number of electrons meaning there are also 29 electrons. Fig. 2 Bohr’s Model of Cu Atom with 29 electrons
- 8. CHARGES Electricity is theflow of electric charges and bear in mind that there are two charges that we have in electricity. The positive (+) and the negative (-) charges. These two are vital so as to have flow of electric charge. In order to have a flow there’s a need for charge carrier. These are particles or holes that freely move within a material and carry an electric charge. Most of the time charge carriers are negatively charged. Please bear in mind that the electrons and protons both carry the same charge but in different type. Coulomb's law Also known as electrostatic force that operates between charges. In other words this force make possible the attraction and repulsion. As a rule unlike charges attract while like charges repel. Positive + Positive = Repel Positive + Negative = Attract Negative + Negative = Repel HOW CHARGES FLOW The trick is simple, since electron is in the outer part of an atom it is easier to make it flow as compared to the proton. If then the electrons flow then there will be an electricity. By making the electron a free state and applying force with the same negative charge then flow will take place. Let’s look at the copper with 29 electrons and protons. Electrons orbit at varying distances from the nucleus of the atom. Electrons closer to the nucleus feel a much stronger attraction to the center than those in distant orbits. The outermost electrons of an atom are called the valence electrons, these require the least amount of force to be freed from an atom. Using enough electrostatic force on the valence electron--either pushing it with another negative charge or attracting it with a positive charge--we can eject the electron from orbit around the atom creating a free electron. Then let us now consider a normal copper wire composed of so many copper atom. As a free atom enters to a copper atom its valence electron will be then pushed to another atom and so on and so forth. In a stricter sense there will be a domino effect in the whole copper wire as a result there will be an electric current or flow of electric charge.
