Essay about Btec L3

In the article "Energy Story". I learned that electricity figures are everywhere and where electricity comes from. Did you know that electricity comes from atoms? atoms are the proton, the neutron, and the electron. Nevertheless, electrons contain negative charge, protons are positive and neutrons are neutral, I also learned that a charged atom is called an ion.

The National Health Service (NHS) is an organisation in the Public sector, this means that it is provided and funded by the government through taxes, and it provides a service. It is health care system, provided to anyone regardless of age, race and income; free of charge to prevent diseases and illnesses. It was founded in 1948 with the aims to improve the quality and length of life of local people; to provide better services where they are needed most; and to help people to take more control of their health. Although one of its aims is to provide a service to the local people, the NHS is a national

2a. Consumers would certainly see a hike in prices on the imported product and in turn could affect the consumer’s ability to afford neither the domestic made clothing nor foreign made clothing.

What is an electrical circuit? How can you manipulate components and design a circuit that will do what you want it to? This guided activity will introduce you to some components, tools, and concepts that are fundamental in electronics. It will allow you to investigate and discover:

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

In the first couple of words it says “An electric current is a flow of electric charge”. In the first sentence it already gets in to talking about electric currents and how they flow through an electric charge. In the first sentence in Energy Story it talks about how “Electricity figures everywhere in our lives”. Both the articles get right in about talking about electricity. In the first seconds of the video she talks about her belief in education and how she found a way to make electricity out of homemade playdough or store-bought play dough. My conclusion is to think of what is around

To understand how this electricity works we must start with the basics. The atom is the smallest unit of matter, consisting of protons, neutrons, and electrons. Protons have a positive charge, neutrons have no charge, and electrons have a negative charge. Electric charges that are the same repel each other and charges that are different attract each other. Electric charges can exist alone, unlike magnetic poles.

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

Where would we be without electricity today? Electricity has changed the world as we know it and is always advancing. Have you ever thought about who helps keep it under control or who installs the wires capable of moving electricity from room to room in your house? Most likely you have never wondered, until the moment it goes out or has problems. This is where one would find out that an electrician can help with these problems.

Being a partner is "a strong motivating factor," "You're not just an employee; you are an owner of the business. That makes you feel differently about everything."(Tom Miller department store director at JMP)

When electrons flow in the battery, it creates an electrical current that powers things. The battery puts the right chemicals in the right relationships, and then puts a wall between them. When the two opposite sides of a battery are connected by a conductor, the electrons flow (The Columbia Encyclopedia, 6th ed., 2012). The three main parts of

An alternating current (AC) will describe how the charges of electricity is able to travel in either direction when it is necessarily needed. This alteration changes the voltages and causes it to go back in reverse in the way the current does.

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.
