Electricity and Magnetism Spring Lab Project

Electric Field Hockey Objective: Write two paragraphs. Explain the challenges of scoring goals in this game. Be sure to include in your explanation the terms positive and negative charge, electric field line and explain how mass affects the motion of the “puck.” This simulation project is all about getting the puck into the goal while surround the puck with using few positive and electric charges. The positive charges have made the puck bounce back off, while the negative charges have…

10 American Inventions That Changed the World

From the mundane to the truly spectacular, numerous American inventions have changed the world. Here is a countdown of ten things invented by Americans that have become part of our everyday lives here and across the world. 10. If you find buttons quite a fuss as you dress up for work, then you have to thank Whitcomb L. Judson, an inventor from Chicago, for inventing the clasp locker, the zipper’s predecessor which was introduced in 1893. The modern design was…

Electrical Circuit

1. Conductor – is a material which contains movable electric charges. In metallic conductors such as copper or aluminum, the movable charged particles are electrons (see electrical conduction). Positive charges may also be mobile, such as the cationic electrolyte(s) of a battery, or the mobile protons of the proton conductor of a fuel cell. In general use, the term “conductor” is interchangeable with “wire. 2. Insulators – are non-conducting materials with few mobile charges and which support only insignificant electric…

Electrostatics Paper

Electrostatics is a part of physics is that the study and analysis of electricity, its properties and its applications. Electrostatics was discovered when an ancient Greek philosopher named Thales. In 600 B.C., Thales learned that when he rubbed amber with fur, it would start to attract other lightweight objects such as feathers and dust which is now known as a process called triboelectrification. This is also how we got the word electricity, which comes from the Greek word, elektron, which…

Biography of Georg Simon Ohm

Georg Simon Ohm (16 March 1787 – 6 July 1854) was a Bavarian (German) physicist and mathematician. As a high school teacher, Ohm began his research with the new electrochemical cell, invented by Italian scientist Alessandro Volta. Using equipment of his own creation, Ohm found that there is a direct proportionality between the potential difference (voltage) applied across a conductor and the resultant electric current. This relationship is known as Ohm’s law. Ohm died in Munich in 1854, and is…

Voltmeter and Ammeter

Measuring Voltage Measuring the voltage between two points of an electrical current can be done with an instrument called a voltmeter. One type of voltmeter is a direct-current voltmeter. When taking a voltage reading the instrument is placed across the portion of the circuit that is to be measured. Direct-Current Voltmeter The direct-current voltmeter has a horseshoe shaped magnet, with a semicircular piece of soft iron attached to each end of the magnet. The iron is also magnetized. The iron…

Investigating the Rate of Electrolysis

It is known that by passing a constant electric current through a copper sulphate solution the passage of ions through this solution results in copper atoms being dissolved into the solution from the anode, which has a positive charge while positive copper, ions (cations) are also being discharged at the cathode which has a negative charge. Normally anions, which have a negative charge, are discharged at the anode. The experiment I will be carrying out is aimed to observe the…

Report Writing

Eve-teasing is a widespread and most disturbing reality for the girls in Bangladesh. We hardly find reports of eve-teasing in the media until it ends up causing some serious damage to somebody. But we do come across, at times, news and reports telling us how terrifying the consequences of eve-teasing can be. And such news does not usually attract public attention until it grows into a national issue. According to figures released by the Ain-O-Shalish Kendra (ASK) human rights organization,…

Coulomb’s Law

ABSTRACT Performing this experimentation will allow one to investigate the relationship quantitative relationship between the electrostatic force and the distance between charged objects. First a simply observation was made of the electrical forces on two pieces of tape taking note of their attraction and repulsion. This same phenomenon was observed in the experimentation of two charged spheres. Furthermore the we used this experimentation to determine the magnitude of the electrical force between charged objects through video analysis. Derived from our…

Electricity Generation Using a Wind Turbine

Wind turbines are machines built for generation of electricity. The electric power is generated by harnessing the wind speed to drive the shaft that connects to the gears assembled to amplify the amount of energy produced. Aside from wind power, other forces, like gravity and thermal energy, also affect the rotation of the blades, which in turn affect the electricity generation process. This research is aimed at creating a simple wind turbine that is capable of generating electricity. The process…

Electric Generator

Early 20th century alternator made inBudapest, Hungary, in the power generating hall of a hydroelectric station In electricity generation, an electric generator is a device that converts mechanical energy to electrical energy. A generator forces electric charge (usually carried by electrons) to flow through an external electrical circuit. The source of mechanical energy may be a reciprocating or turbine steam engine, water falling through a turbine or waterwheel, aninternal combustion engine, a wind turbine, a hand crank, compressed air, or…

Cross Cultural Competency

You have no choice about which culture programs you from birth. So don’t judge others because of their cultural differences from you. All complex societies (such as our own) contain subcultures that share the larger cultural outlook, but have significant differences. The culturally savvy Soldier will take an active interest in any culture he or she works in. ReALLIT: read, ask, look, listen, investigate, and think. Look for styles of interaction/proper behavior, greeting rituals, local dress, daily routines and movements,…

Smart Grid

The current electricity infrastructure in the Unites States consists of one way “communication” between the electric company and the homes receiving the electricity with the communication coming from the electric company to the homes. The current electricity infrastructure in the United States is more than 100 years old and because of this fact, it is outdated resulting in a great lack of efficiency. There is no way for the electricity company to obtain information from the individual homes pertaining to…

Science Report on Electromagnetism

This report will be done on the theory of Electromagnetism. Electromagnetism is the force that combines electricity and magnetism. Electromagnetism is found in everyday things that shape our lives. It is the cleanest force used to make energy today, and it is used in almost every home appliance that is in a standard middle classed home. The E-M force is the most commonly under looked force that helps us live. Without Electromagnetism, we would be falling through floors, literally! E-M…

Automatic Meter Reading

Automatic meter reading is the technology of automatically collecting consumption, diagnostic, and status data from water meter or energy metering devices (gas, electric) and transferring that data to a central database for billing, troubleshooting, and analyzing. This technology mainly saves utility providers the expense of periodic trips to each physical location to read a meter. Another advantage is that billing can be based on near real-time consumption rather than on estimates based on past or predicted consumption. This timely information…
