In order to answer the question what is electricity, first we must start off with talking about an atom. An atom is made up of protons neutrons, and electrons. The protons (positive charge) and neutrons (neutral charge) form the nucleus, while the electrons (negative charge) orbit around the nucleus. The atom is considered balanced if the protons and electrons are the same. But, if the atom loses or gains an electron it becomes an unbalanced atom. Losing electrons makes the atom have a positive charge because there are more positively charged protons than electrons. Gaining electrons make the atom have a negative charge because there are more negatively charged electrons than protons. Since there is a missing electron, either the electron that was lost looks for another atom with a missing electron to join or the atom with the missing atom will look for a lone electron to pair join to it. The transfer of electrons is what causes electricity. When the electrons move from one atom to another they create a flow or current of electricity. Scientists are able to purposely make atoms lose their electrons, so that they make electricity. (www.energyquest.ca.gov)
There are many different sources to create electricity. Some better than others for various reasons but all the major ways to make electricity are nuclear fission, nuclear fusion , solar panels, oil, coal, wind windmills, tidal energy, biomass, natural gas, geothermal, man/animal power, hydro-electric, magnetic, and fuel cell. Nuclear fission involves taking a Uranium atom and splitting the nucleus in half, which then creates a lot of power. (www.energyquest.ca.gov)

• Creates very large amounts of energy
• No air pollution
• Uranium can be found anywhere
• We are not going to run out anytime soon
• Cheap to operate
Cons
• Making the power plants is
In the article,"Energy Story", it tells you all about basic energy and how scientists found out how it works. It tells you about each part of an electron and what part is what. The center is called the Nucleus. Electrons and atoms move together to create what is known as electricity. Atoms and electrons flow through an object
Its most known process of generating electricity would be movement of air through wind turbines. Wind power has two parts, mechanical and electrical systems. Mechanical systems are low speed and are used for mechanical tasks such as pumping water or grinding grain. Electrical systems are high speed and are used to generate electricity to power homes or schools. Many people feel that wind farms full of turbines, are aesthetically unpleasing, but wind power is a clean energy source and does not generate greenhouse gas emissions. It is a very abundant resource throughout the United States. Wind power is simple, relatively cheap, and low maintenance (Sambu). Wind power is again, free and very abundant so no matter how much we use now, we will still obtain enough in the
All these effects were the cause of the discovery of nuclear fission and its properties. Nuclear Fusion Nuclear fusion is the process used by the sun and the stars in our solar system to produce their energy. Fusion involves smashing hydrogen atoms together at high velocities to form helium, and the matter is made into energy.
Nuclear energy must be a consideration for the future with the rapidly depleting supply of fossil fuels. This type of energy can be created through nuclear fission and nuclear fusion. Nuclear fission is the splitting of a heavy atom into two or more parts, releasing huge amounts of energy. The release of energy can be controlled and captured for generating electricity. Nuclear fusion involves bombarding hydrogen atoms together to form helium. In the long run, nuclear fusion has greater potential than fission.
The major sources of energy in the US from highest percentage to lowest percentage are oil, coal, natural gas, nuclear fuels, renewable energy
Nuclear energy is produced during the process named nuclear fission or nuclear fusion. The development of nuclear energy started in the 20th century and there is now worldwide recognition for using nuclear energy. Popular countries that operates nuclear power are United States, France, Japan, and Russia, the nuclear energy generates up to 6% of the world’s electricity supplies. Even though the energy is mostly used by many countries, but it may causes side effect to the living things in the environment. (WNA, 2012)
A battery is a device which converts chemical energy into electrical energy. A battery usually consists of two or more cells connected in series or parallel, you can also have a single cell battery. All cells consist of a positive electrode, and a negative electrode. An electrolyte is a liquid substance capable of conducting electricity. In this substance one of the electrodes will react producing electrons, while the other will except electrons. When the electrodes are connected to a device to be powered, called a load, an electrical current flows.
The free electrons are given energy and as a result, move and collide with neighbouring. free electrons. This happens across the length of the wire and thus electricity is conducted in the building. Resistance is the result of energy lost as heat. The sand is hot.
The cheapest way to generate electricity, today, is hydropower. The reason for that is, once a dam has been constructed and equipment installed, the source of the energy is free. It is a fuel source that is renewable because of things like snow and rainfall. Engineers may control the water flow on demand.
To begin, nuclear power is produced by nuclear fission, which is the splitting of an atom to start a chain reaction (“11 Facts”). This chain reaction produces massive amounts of heat. Nuclear reactors take advantage of this heat by pumping water into the reactor, which in turn produces steam. The steam then becomes pressurized through a pipeline and exits into a turbine (“How do Nuclear”). The pressurized steam causes the turbine blades to spin, producing power which is linked to a generator for use in the main power lines. When the steam passes the turbine blades, it goes past cooled pipes and condensates (“How do Nuclear”). After the condensation process is finished and the steam reverts back to water, it is pumped into the reactor again, thus completing the process of producing nuclear-based power.
All useful generators of electricity come in two basic forms, alternating current and direct current. Direct current (dc) comes from generators that do not change in polarity, always producing a positive charge. In alternating current (ac) the polarity of the terminals is always changing from positive to negative. Thus you are left with alternating current flow. There are different ways of measuring and generating alternating and direct current.
Electricity is one of the chief products of the oil industry. We use oil to heat our homes and businesses. We use oil to produce electricity to light our homes and businesses also.
Power equals influence. It 's personal, too, residing within those who wield it. Sometimes a position of authority within an organization lends power to a person, but borrowed power isn 't necessarily as effective as power derived from leadership. Every organization has leaders who hold no positional authority, yet somehow wield influence, while managers who should be able to command respect flounder. Small-business owners wanting to enhance their influence and that of their managers should consider the five sources of power available at organizations. Three come with position. The other two are available to anyone.
Though there is still much to know about the nature of electricity, there is a basic understanding of its essence. As mentioned previously, electricity is a form of energy from the existence of charged particles. To thoroughly understand electricity, it is imperative to first analyze electric force. Coulomb’s law summarizes the electric force between two objects. Coulomb’s law is written as F= k_e (|q_1 ||q_2 |)/r^2 , where ke is 8.9875 x 109 N x m2 /C2. As shown in the equation, the separation distance of the charged particles is on the bottom of the fraction. This means that a greater distance would yield a lower force. Electricity can be classified in two different ways: static electricity or current electricity. In static electricity, there is a transfer of electrons between
Nuclear energy is generated by a process called fission. Fission occurs within the reactor of a nuclear power plant when a neutron is fired at an atom of uranium causing it to split and release subsequent neutrons.1 These are able to crash into other uranium atoms causing a chain reaction and releasing a great deal of heat energy.
