  • Printer Tech Tips—Cause & Effects of Static Electricity in Paper
    Printer Tech Tips Cause & Effects of Static Electricity in Paper Problem The paper has developed a static electrical charge causing an abnormal sheet-to- sheet or sheet-to-material attraction which is difficult to separate. This condition may result in feeder trip-offs, print voids from surface contamination, ink offset, Sappi Printer Technical Service or poor sheet jog in the delivery. 877 SappiHelp (727 7443) Description Static electricity is defined as a non-moving, non-flowing electrical charge or in simple terms, electricity at rest. Static electricity becomes visible and dynamic during the brief moment it sparks a discharge and for that instant it’s no longer at rest. Lightning is the result of static discharge as is the shock you receive just before contacting a grounded object during unusually dry weather. Matter is composed of atoms, which in turn are composed of protons, neutrons, and electrons. The number of protons and neutrons, which make up the atoms nucleus, determine the type of material. Electrons orbit the nucleus and balance the electrical charge of the protons. When both negative and positive are equal, the charge of the balanced atom is neutral. If electrons are removed or added to this configuration, the overall charge becomes either negative or positive resulting in an unbalanced atom. Materials with high conductivity, such as steel, are called conductors and maintain neutrality because their electrons can move freely from atom to atom to balance any applied charges. Therefore, conductors can dissipate static when properly grounded. Non-conductive materials, or insulators such as plastic and wood, have the opposite property as their electrons can not move freely to maintain balance.

  • Units and Magnitudes (Lecture Notes)
    physics 8.701 topic 2 Frank Wilczek Units and Magnitudes (lecture notes) This lecture has two parts. The first part is mainly a practical guide to the measurement units that dominate the particle physics literature, and culture. The second part is a quasi-philosophical discussion of deep issues around unit systems, including a comparison of atomic, particle ("strong") and Planck units. For a more extended, profound treatment of the second part issues, see arxiv.org/pdf/0708.4361v1.pdf . Because special relativity and quantum mechanics permeate modern particle physics, it is useful to employ units so that c = ħ = 1. In other words, we report velocities as multiples the speed of light c, and actions (or equivalently angular momenta) as multiples of the rationalized Planck's constant ħ, which is the original Planck constant h divided by 2π. 27 August 2013 physics 8.701 topic 2 Frank Wilczek In classical physics one usually keeps separate units for mass, length and time. I invite you to think about why! (I'll give you my take on it later.) To bring out the "dimensional" features of particle physics units without excess baggage, it is helpful to keep track of powers of mass M, length L, and time T without regard to magnitudes, in the form When these are both set equal to 1, the M, L, T system collapses to just one independent dimension. So we can - and usually do - consider everything as having the units of some power of mass. Thus for energy we have while for momentum 27 August 2013 physics 8.701 topic 2 Frank Wilczek and for length so that energy and momentum have the units of mass, while length has the units of inverse mass.

  • Measuring Electricity Voltage Current Voltage Current
    Measuring Electricity Electricity makes our lives easier, but it can seem like a mysterious force. Measuring electricity is confusing because we cannot see it. We are familiar with terms such as watt, volt, and amp, but we do not have a clear understanding of these terms. We buy a 60-watt lightbulb, a tool that needs 120 volts, or a vacuum cleaner that uses 8.8 amps, and dont think about what those units mean. Using the flow of water as an analogy can make Voltage electricity easier to understand. The flow of electrons in a circuit is similar to water flowing through a hose. If you could look into a hose at a given point, you would see a certain amount of water passing that point each second. The amount of water depends on how much pressure is being applied how hard the water is being pushed. It also depends on the diameter of the hose. The harder the pressure and the larger the diameter of the hose, the more water passes each second. The flow of electrons through a wire depends on the electrical pressure pushing the electrons and on the Current cross-sectional area of the wire. The flow of electrons can be compared to the flow of Voltage water. The water current is the number of molecules flowing past a fixed point; electrical current is the The pressure that pushes electrons in a circuit is number of electrons flowing past a fixed point. called voltage. Using the water analogy, if a tank of Electrical current (I) is defined as electrons flowing water were suspended one meter above the ground between two points having a difference in voltage.

  • Lecture 10: Tidal Power
    Lecture 10: Tidal Power Chris Garrett 1 Introduction The maintenance and extension of our current standard of living will require the utilization of new energy sources. The current demand for oil cannot be sustained forever, and as scientists we should always try to keep such needs in mind. Oceanographers may be able to help meet society's demand for natural resources in some way. Some suggestions include the oceans in a supportive manner. It may be possible, for example, to use tidal currents to cool nuclear plants, and a detailed knowledge of deep ocean flow structure could allow for the safe dispersion of nuclear waste. But we could also look to the ocean as a renewable energy resource. A significant amount of oceanic energy is transported to the coasts by surface waves, but about 100 km of coastline would need to be developed to produce 1000 MW, the average output of a large coal-fired or nuclear power plant. Strong offshore winds could also be used, and wind turbines have had some limited success in this area. Another option is to take advantage of the tides. Winds and solar radiation provide the dominant energy inputs to the ocean, but the tides also provide a moderately strong and coherent forcing that we may be able to effectively exploit in some way. In this section, we first consider some of the ways to extract potential energy from the tides, using barrages across estuaries or tidal locks in shoreline basins. We then provide a more detailed analysis of tidal fences, where turbines are placed in a channel with strong tidal currents, and we consider whether such a system could be a reasonable power source.

  • On the Nature of Electric Charge
    Vol. 9(4), pp. 54-60, 28 February, 2014 DOI: 10.5897/IJPS2013.4091 ISSN 1992 - 1950 International Journal of Physical Copyright © 2014 Author(s) retain the copyright of this article Sciences http://www.academicjournals.org/IJPS Full Length Research Paper On the nature of electric charge Jafari Najafi, Mahdi 1730 N Lynn ST apt A35, Arlington, VA 22209 USA. Received 10 December, 2013; Accepted 14 February, 2014 A few hundred years have passed since the discovery of electricity and electromagnetic fields, formulating them as Maxwell's equations, but the nature of an electric charge remains unknown. Why do particles with the same charge repel and opposing charges attract? Is the electric charge a primary intrinsic property of a particle? These questions cannot be answered until the nature of the electric charge is identified. The present study provides an explicit description of the gravitational constant G and the origin of electric charge will be inferred using generalized dimensional analysis. Key words: Electric charge, gravitational constant, dimensional analysis, particle mass change. INTRODUCTION The universe is composed of three basic elements; parameters. This approach is of great generality and mass-energy (M), length (L), and time (T). Intrinsic mathematical simplicity that simply and directly properties are assigned to particles, including mass, postulates a hypothesis for the nature of the electric electric charge, and spin, and their effects are applied in charge. Although the final formula is a guesswork based the form of physical formulas that explicitly address on dimensional analysis of electric charges, it shows the physical phenomena. The meaning of some particle existence of consistency between the final formula and properties remains opaque.

  • Electricity Production by Fuel
    EN27 Electricity production by fuel Key message Fossil fuels and nuclear energy continue to dominate the fuel mix for electricity production despite their risk of environmental impact. This impact was reduced during the 1990s with relatively clean natural gas becoming the main choice of fuel for new plants, at the expense of oil, in particular. Production from coal and lignite has increased slightly in recent years but its share of electricity produced has been constant since 2000 as overall production increases. The steep increase in overall electricity production has also counteracted some of the environmental benefits from fuel switching. Rationale The trend in electricity production by fuel provides a broad indication of the impacts associated with electricity production. The type and extent of the related environmental pressures depends upon the type and amount of fuels used for electricity generation as well as the use of abatement technologies. Fig. 1: Gross electricity production by fuel, EU-25 5,000 4,500 4,000 Other fuels 3,500 Renewables 1.4% 3,000 13.7% Nuclear 2,500 TWh Natural and derived 31.0% gas 2,000 Coal and lignite 1,500 19.9% Oil 1,000 29.5% 500 4.5% 0 1990 1991 1992 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 2010 2020 2030 Data Source: Eurostat (Historic data), Primes Energy Model (European Commission 2006) for projections.

  • Hydroelectric Power -- What Is It? It=S a Form of Energy … a Renewable Resource
    INTRODUCTION Hydroelectric Power -- what is it? It=s a form of energy … a renewable resource. Hydropower provides about 96 percent of the renewable energy in the United States. Other renewable resources include geothermal, wave power, tidal power, wind power, and solar power. Hydroelectric powerplants do not use up resources to create electricity nor do they pollute the air, land, or water, as other powerplants may. Hydroelectric power has played an important part in the development of this Nation's electric power industry. Both small and large hydroelectric power developments were instrumental in the early expansion of the electric power industry. Hydroelectric power comes from flowing water … winter and spring runoff from mountain streams and clear lakes. Water, when it is falling by the force of gravity, can be used to turn turbines and generators that produce electricity. Hydroelectric power is important to our Nation. Growing populations and modern technologies require vast amounts of electricity for creating, building, and expanding. In the 1920's, hydroelectric plants supplied as much as 40 percent of the electric energy produced. Although the amount of energy produced by this means has steadily increased, the amount produced by other types of powerplants has increased at a faster rate and hydroelectric power presently supplies about 10 percent of the electrical generating capacity of the United States. Hydropower is an essential contributor in the national power grid because of its ability to respond quickly to rapidly varying loads or system disturbances, which base load plants with steam systems powered by combustion or nuclear processes cannot accommodate. Reclamation=s 58 powerplants throughout the Western United States produce an average of 42 billion kWh (kilowatt-hours) per year, enough to meet the residential needs of more than 14 million people.
