How electrostatics influence our lives

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.

Benjamin Franklin and the Lightning Rod- In 1750 Benjamin Franklin set out to prove that lightning was electricity. Franklin constructed an iron rod with a sharpened end and grew impatient because it wasn’t conducting. He theorized that his sharp iron lightning rod did not conduct any electricity so many people used them for protection from

The current has a positive charge in one side of the coil and it transforms to negative when it gets to the other side of the coil. This charge controls the magnetic field, making the like charges repeal and the opposite charges attract.

You're going to want to want to add a drop on a microscope slide, and observe their behaviors first without anything added. Next, you need to add an equal volume of 500 microliters of 1% India Ink to the cells. Before you sample that, you need to micropipette 20 microliters of cells + ink suspension into a microcentrifuge tube and add 10 microliters of 3% glutaraldehyde of to the tube. Lastly, you're going to count the number of vacuoles with ink per cell (at least 10 cells) at 0minutes. Record your information, and then you will continue to record the results at 5, 10, 20 and 30 minutes in the

In the story "Energy story" it talks about the structure of an atom and electrons and how electrons can move easier in somethings than in other things, like in paragraph 21-22 it says that thing like rubber cloth glass and dry air are good insulators, which means that electrons don’t move as well as in things like copper, aluminum, and steel.

In paragraph two, it states "Pure water contains very few ions, so it does not conduct electricity well. When table salt is dissolved in water, the solution conducts very well, because the solutions contain ions.". In paragraph four, it explains how laundry ammonia can conduct electricity. It states "When ammonia dissolves in water, it reacts with the water and forms a few ions.". In conclusion, paragraph five explains more about how ammonia can cause electricity when it is put into a solution with vinegar.

The cause of static electricity is when there is an unbalanced molecular construction or non conductive insulators such as plastic, glass, ceramics, and other non conductive materials

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

Q9. There are several everyday life situations where we experience this electricity - now we can be more precise and say it is static electricity. Give two examples of everyday life experiences that you can think of and that were not covered here. Describe whether the charging is due to friction, charge separation, or charging by induction.

Lightning is basically a large amount of static electricity. An individual can create a small amount of “lightning” by rubbing a balloon with carpet which produces a relatively small amount of static electricity. Lightning is formed when charged particles in a cloud become polarized and separate significantly with positive charges moving up and negative charges moving

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.

Printmaking was a well known and widely used form of art during the late 15th and early 16th century Renaissance. Although this was late in the time period, Rembrandt was known for his etchings and drypoints. The process of etching and engraving is carried out by taking a metal or copper plate and covering it with an acid-resistant substance. The printmaker draws into the metal, exposing the plate. “Acid is then used to

An electricity and magnetism phenomenon apparently unrelated to power are electrical magnetic fields. We are familiar with these forces through the interaction of compasses with the earth's magnetic field, or through fridge magnets or magnets on children's toys. Magnetic forces are explained in terms very similar to those used for electric forces:

The threshold frequency varies with each metal. When the sodium plate was exposed to high frequency light, electrons were emitted and were attracted to the positive terminal, causing a flow of current. However, when a low frequency light was used no electrons were emitted and therefore there was no current. Observations of the Photoelectric Effect 1. Current flows as soon as the negative terminal is illuminated.

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.
