Citrus Fruit Electricity Essay

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.

* Protons and electrons have equal and opposite electrical charges. Protons are positively charged, and electrons are negatively charged.

In the video, "Hands-On Science with Squishy Circuits", Anne Marie Thomas does a TED talk about Play-Doh circuits. She explains how she teaches her daughter about electricity by making homemade Play-Doh. At 1:42, she demonstrates with an LED light, Play-Doh that contains salt, Play-Doh that contains sugar, and batteries. She splits the salty Play-Doh in two and connects them with the batteries. To conclude, she sticks the LED light in both of the "squishy circuits" and it turns on.

When the blackberry cell was perpendicular to the ground, the multimeter measured a current of .4 microamps. The other orientations produced currents ranging from 0 to .3 microamperes, never reaching the maximum current at 0 degrees. This effect was replicated in the second week of the lab. Although Table 4 shows that all the measured currents were zero, the multimeter switched between negative zero and positive zero as the cell was rotated. As it tended to be negative when the cell was facing downward, it is likely the current was simply not strong enough to be measured. However, when the cell was facing up, the current was found to be positive, meaning that the current must have decreased as the cell was rotated downwards. Based on this data, it is likely a solar cell of this type would have a small range of angles at which it could be effective, limiting the places solar cells could be

One of these properties is called an electrical charge. Protons have a "positive" (+) charge, electrons have a "negative" (-) charge, and neutrons have no charge, they are neutral.

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 nucleus of an atom there are protons and neutrons the number of protons and neutrons depends on the element and ,if it is an isotope of that element. E.g. carbon 12, carbon 12 has six neutrons six protons and 6 electrons . Electrons are located around the nucleus of the atom. Electrons are in shells, the shell closest to the nucleus is 1 , the one after 2 and so on. Each shell can only hold up to a certain number of electrons . the first can hold up to 2 , the second 8 (2+6) the third up to 18 (2+6+10). The general formula for finding out how many electrons a shell can hold is 2n^2. Electrons have a negative charge , while protons have a positive and neutrons have no charge. A atom has the same number of protons and electrons. An ion is formed when an atom loses or gains a electrons .

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 EPA estimates Americans purchase nearly 3 billion batteries each year (D., 2009). A battery is also known as a voltaic cell, and the energy generated and stored by a battery is actually a result of chemical reactions and not mechanical motion. Batteries are contained in nearly every common electronic device, ranging from small devices like smartphones to larger scale products like automobiles, and chemistry is the driving force behind the function of these batteries.Batteries consist of galvanic cells that carry out the production and storage of electrical energy from chemical reactions. The chemical reactions going on inside of the battery are between the oxidant and reductant of Copper and Zinc metals in there Copper-Zinc Voltaic

Materials, paper, wires, stop watch, battery holders, metal connectors, computer, light bulbs, and graph paper. Batteries, Duracell, Everready, Energizer, and Rayovac, Panasonic. I researched on how a battery produces electricity. two most common types of batteries. Alkaline batteries are made with potassium hydroxide, which is a basic solution meaning it can neutralize an acid. A non al battery is made with ammonium chloride and zinc. The ammonium chloride is acid. Alkaline batteries tend to be more expensive than their non-alkaline counterparts, just like brand-name batteries are more expensive

The chemical reaction which occurs between the electrolyte and the positive electrode internally in the battery then produces a buildup of positive ions, which are atoms that are missing electrons. The positive ions buildup at the cathode of the battery which

The atom is a unit of matter, the smallest unit of an element, consisting of a dense, central, positively charged nucleus surrounded by a system of electrons, equal in number to the number of nuclear protons. It consists of a core nucleus surrounded by negatively charged electrons. Inside the atom nucleus contains a mixture of positively charged protons, and electrically neutral neutrons. All electrons bind to the nucleus through an electromagnetic force. A ground of electrons bound together form individual molecules. An atom with an equal number of protons and electrons will hold a neutral charge. An ion has either a positive or negative charge because of a lack of electrons or an electron excess. The number of protons determines the

An Atom is the the basic building block of all matter. Atoms are made up of Particles, called: Protons, neutrons and Electrons. Protons carry a positive charge, the neutron carry 's a neutral charge and the electron carry’s a negative charge. The Atom has two main parts the Nucleus and the Electron Shell. The Nucleus contains the Protons and Neutrons. The electron Shell Contains the The electrons.

Oranges have been a staple of eating healthy for thousands of years, and the fruit probably originated somewhere in Southeast Asia. Historical records of oranges date back as far as China, more than 4,500 years ago. It is one of the most popular citrus fruits, and its scientific name is

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.
