    Power Factor

    1907 words, 8 pages

    The power factor of an AC electric power system is defined as the ratio of the real power to the apparent power, and is a number between 0 and 1 (frequently expressed as a percentage, e.g. 0.5 pf = 50% pf). Real power is the capacity of the circuit for performing work in a particular time. Apparent power is the product of the current and voltage of the circuit. Due to energy stored in the load and returned to the source, or due to a non-linear load that distorts the wave shape of the current drawn from the source, the apparent power can be greater than the real power. Low-power-factor loads in

    1. Abstract In 2001, The State of Environment report clearly shows the buildings add negative impact to our natural environment up to 32% of the world’s resources, including 12% of the fresh water and up to 40% of the world’s energy. Buildings also generate 40% of waste to landfill and 40% of air emission.1 Ecologically Sustainable Design (ESD) was such a trend nowadays. What is sustainability? In 1990, Australian Government defined ESD as: 'using, conserving and enhancing the community's resources so that ecological processes, on which life depends, are maintained, a

    Tidal Power An Alternative Erergy Source

    1027 words, 5 pages

    Tidal Power is an alternative energy source that converts energy from the ocean into electricity and other forms of power. Out of all alternative energy sources, tidal power is the most reliable and predictable and has been used for many centuries. There are three basic categories of getting tidal energy; by using the oceans waves, the tides and the temperature differences in the water. It is a more beneficial energy source then using fossil fuels as it doesn’t actually use the water; instead it uses the energy produced from the water. Tidal power has problems such as i

    Solar Energy

    2606 words, 11 pages

    SOLAR ENERGY. All life on Earth depends on energy from the sun. Solar energy is the source of energy for photosynthesis. It provides the warmth necessary for plants and animals to survive. The heat from the sun causes water on the Earth's surface to evaporate and form clouds that eventually provide fresh rainwater. Solar energy is the result of thermonuclear fusion reactions deep within the sun. These reactions produce so much energy that they keep the surface temperature of the sun at about 10,300B0F (5,700B0C). Even though solar energy is the largest source of energy received by the Eart

    Wind Energy

    2552 words, 11 pages

    Wind Power is the conversion of wind energy into a useful form, such as electricity, using wind turbines. At the end of 2007, worldwide capacity of wind-powered generators was 94.1 gigawatts.[1] Although wind produces about 1% of world-wide electricity use,[2] it accounts for approximately 19% of electricity production in Denmark, 9% in Spain and Portugal, and 6% in Germany and the Republic of Ireland (2007 data). Globally, wind power generation increased more than fivefold between 2000 and 2007.[1] The principle application of wind power is to generate electricity. La

    Obedience Essay

    1645 words, 7 pages

    Obedience is the result of social influence; the unerring compliance to the will of something or someone. Examples of this are all around us in society where someone in authority expects us to behave in a certain way in a particular situation. In childhood this could be a parents request for a certain kind of behaviour or a teacher in a school environment expecting compliance to the rules and regulations. This continues in adult hood with the expectation to comply with the law of the land. Over the years psychologists have been perplexed by the acts of certain people

    Green energy, a term used for sources of power and energy that is environmentally friendly. Hybrid vehicles, consumption of energy, and solar panel energy are efficient and inefficient ways to provide energy for your everyday needs. Green energy's main focus is to use sources that can cut down on pollution, and that’s why it’s so hard in this day and age to get people to agree in these subjects. These subjects always bounce back and forth between engineers, debating if these new energy sources really help us in this day and age. Reviewing these subjects show the expansion of solar power const

    A lemon battery is a battery used in experiments proposed in many science textbooks around the world.  It is made by inserting two different metallicobjects, for example a galvanized nail and a copper coin, into an ion bridge (for example a lemon, a potato or paper soaked in salt water or acid). The copper coin serves as the negative electrode or cathode and the galvanized nail as the electron-producing positive electrode or anode. These two objects work aselectrodes, causing an electrochemical reaction which generates a small potential difference. The origin of lemon and potato batteries is u

    How energy can be converted from one form to another. Energy conversion is the process of changing one form of energy to another form. In order for a system to gain energy the environment must supply it, and when the system looses energy the environment must gain it. When the energy is transferred it can be converted from its original form to another as the transfer takes place, but the energy will never be created or destroyed.

    Below Zero Kelvin

    951 words, 4 pages

    While it was once thought to be impossible for absolute temperature to be below zero Kelvin, physicists at the Ludwig-Maximilians University Munich recently created an atomic gas that has a negative Kelvin value. These negative values are brought about by inverting the Boltzmann distribution, which means that most particles move slowly, while only some most very fast in a low-energy state. By inverting this distribution so that most particles move fast while only some move slowly, it means that the particles now have a negative absolute temperature. While this inversion seems easy in theory, i

    A p–n junction is a boundary or interface between two types of semiconductor material, p-type and n-type, inside a single crystal of semiconductor. It is created by doping, for example by ion implantation, diffusion of dopants, or by epitaxy (growing a layer of crystal doped with one type of dopant on top of a layer of crystal doped with another type of dopant). If two separate pieces of material were used, this would introduce a grain boundary between the semiconductors that severely inhibits its utility by scattering the electrons and holes. p–n junctions are elementary "building blocks" of

SCE has been leading the way in electricity, with roots that lie in Southern California since the 1880s, when various small companies began experimenting with power generation and transmission. It wasn’t until 1894 that the Los Angeles Edison Electric Company was created. Pioneers and people of vision led California into the new 20th century.
