Physics : Electrical Technology ( B.sc ) Essay

After reading the second article named “Conducting Solutions”, I learned a lot about the different types of mixtures and substances on energy sources. This gave the readers follow up examples from the last article explaining more in

Conductor – conductor is an object or type of material that allows the flow of electrical current in one or more directions. The electrons move easily to the other side, away from the object

An electric current exists when there is a net flow of charge through a given area. Electrons flow from the negatively charged region to the positively charged region. This is usually accomplished by using an electrical conductor which allows the electrons to pass freely through the material (Serway, et al. 709). This flow of electrons can generate heat when collisions between the molecules and electrons occur. These collisions then cause the molecules to break apart thus releasing heat. Some common examples of electrical energy are lightning, static electricity, and wiring outlets (Coleman, et al. 82). For the wildland firefighter, lightning is probably the

When the objects rub together electrons can move to the other object. Charging by conduction is the transfer of electrons by direct contact. Charging by induction is the movement of electrons to one part of an object that is caused by the electric field and second object.

Introduction: Voltage can be thought of as the pressure pushing charges along a conductor, while the electrical resistance of a conductor is a measure of how difficult it is to push the charges along. Using the flow analogy, electrical resistance is similar to friction. For water flowing through a pipe, a long narrow pipe provides more resistance to the flow than does a short fat pipe. The same applies for flowing currents: long thin wires provide more resistance than do short thick wires. The resistance (R) of a material depends on its length, cross-sectional area, and the resistivity (the Greek letter rho), a number that depends on the material. The resistivity

The electrons move because they experience a electric current force in the wire. The battery causes an electric field and the electrons experience a force due to that field. The current flows in the opposite direction of the electrons and the flow of the

There are 3 types of metals for electricity conducting: metallic conductor, semiconductor, and superconductor. Metallic conductors allow the free flow of ions and electrons through a sample; and its conductivity decreases as the temperature increases.

4. I do not conduct electricity and I don’t bond well with other elements. Who am I?

First, the difference between the two articles’, "Energy Story" and "Conducting Solutions" purposes. The article, "Energy story," talks about atoms and what atoms are needed to make electricity. That's the articles purpose, to teach you what atoms are needed to make electricity and the atoms. They put everything you need to know about atoms. How they move, how many atoms are needed in one, etc. Now for the second article, "Conducting Solutions," purpose is different. Its purpose is to say what’s a good conductor and what you can mix so it can be a good conductor. They tell you what you can mix like ammonia and vinegar. The other article doesn't really talk much about conductors and which ones

Copper is basic element with the sign on the periodic Cu. Copper is one of best conductors of all metals. It is second only to silver in its conductivity. “Its abundance tied the world together in telecommunication,” (Wojes par. 1); it has tied us together in communication because it is used in most electronic devices such as cell phones and televisions, allowing us to power them and communicate with each other almost instantly. It is also used in jewelery, architecture, and plumbing.

In " Conducting Solutions" it tells you about energy moving through things. Pure water contains very few ions, so it does not conduct electricity very well. When table salt is dissolved in water, the solution conducts very well, because the solution contains ions. The ions come from table salt, whose chemical name is sodium chloride. Sodium chloride contains sodium ions, which have a positive charge, and chloride ions, which is have a negative charge.

The purpose of the last article “Conducting Solutions” is to inform readers how solutions conduct electricity. I know this because the beginning of the article it starts of by saying “When a solution conducts electricity.” This sentence tells me that the rest of the article is probably going to be about conducting solutions. In addition, the article talks about how ions are carried through the solution to produce electricity. It later talks about what solutions you can use to produce electricity.

Introduction: Resistance occurs when atoms find it difficult to travel along wire because there is a restriction keeping the electricity from flowing. The three types of resistances can include the type of material, length of the wire and the thickness of the wire, these separate components can determine the amount of resistance there is when the flow of

Throughout this research paper, the reader will have a better understanding of the different forms of resistance. Also the reader will have the ability to compare the two types of resistance which were active and passive. And finally the reader will be abl

The outer shell of electrons that orbit the nucleus of an atom is called the valance shell. This is what makes a copper atom conduct. For a copper atom the number of electrons is one. When a charge of electricity is placed in the end of a wire the electrons move into the wire. Since there is only one electron in the valance shell of a copper atom it can be easily dislodged with a small amount of energy causing it to jump to the next atom. This will then cause the valance electron of that atom to jump to the next atom and so forth. This movement happens very fast making it possible for a large number of electrons to move through the wire. An example of a conductive atom is shown figure 1.
