Usam condensing in diverse points of the amplifiers, to connect signals of floors for others and to deviate signals for the mass. Capacitive Reactncia When connecting itself a condenser in a source alternated, each change of tension causes to load or discharge of the condenser, provoking the circulation of a chain. The opposition that the condenser presents to the ticket of this chain under regimen AC, is known as capacitive reactncia, and the same one varies as varies the frequency of signal AC. The capacitive reactncia is given mathematically by: Where XC = capacitive reactncia, measured in ohms f = frequency of signal AC, in Hertz – Hz C = capacity measured in Farads – Dielectric F a dielectric or electric insulator is a substance that possesss high Resistance to the flow of the electric chain. This to play its function correctamente, is chosen through certain requirements, such as: Elevada resistance electric, to guarantee the isolation between the part and the electrode; elevado to be able cooling therefore this must cool the part and the electrode, since the extreme heating can originate fissuration; steady Viscosity therefore must evacuate particles of the zone of cut with effectiveness; Not toxic not to free you substantiate toxic when displayed the temperatures high; Filtrabilidade; to keep particles in suspension facilitating the posterior filtering; Elevado latent heat, therefore must be resistant the high temperatures and the oxidation preventing the degradation; Corrosive No not to corrode the constituent components of the machine; transparency to facilitate the visualization of the work zone.

This model has been designed by students of University CEU Herrera Cardinal of Valencia. It is equipped with a hydrogen fuel battery. It thus surpasses in a 40% the record set in 2010, when it crossed 1,802 kilometers. The electrical car with fuel battery of hydrogen designed by students of University CEU Herrera Cardinal of Valencia, has beaten a new record in Germany when surpassing the 2,500 kilometers of route with the fuel equivalent to a liter of gasoline. According to an official notice of the University, IDEA CEU Car has participated in the European competition Shell Echo, that has finalized east Saturday in the German circuit EuroSpeedway de Lausitz. Here, the vehicle has beaten the new record from Spain when crossing 2,534 kilometers with hydrogen equivalent to a liter of gasoline, surpassing in a 40 percent the mark obtained in 2010, that was of 1,802 kilometers. In the electrical motor of IDEA CEU Car, the pressurized, combined hydrogen with the air, it generates the electricity necessary to circulate without no type of polluting emission, since the unique remainder that takes place is water. The students and investigators of Grado and Posgrado de Ingeniera of the CEU-UCH have developed from the year past east system of hydrogen propulsion, to obtain that the vehicle is most efficient possible and crosses the maximum number of kilometers with the minimum power consumption and without no contamination. In October, IDEA CEU Car also gained the Spanish test of ecological vehicles, Lot RACE of Murcia, obtaining the best mark of the 21 participant equipment. The last tests for the completion of the car, previous to Shell Echo 2011, have been realised in the circuit Ricardo Tormo de Cheste, according to the sources, that they have indicated that for their design different aerodynamic testings were realised in the National Institute from Tcnica Aeroespacial (INTA) of Madrid.

Electricity price compare easily and quickly with the power calculator whether cheap or green electricity: electricity prices continue to increase. Rising energy costs can not be prevented and yet electricity customers can actively contribute, to reduce their electricity bill. A provider or change of tariffs can annually save few hundred euros. Flat-screen TVs, washing machines, PC, notebook, Smartphone more and more electronic devices move into our households and consume lots of power here. “While otherwise a meanness is Geil” mentality prevails, many households are not aware this important price driver. Month after month and year after year to pay expensive electricity. Many resent the ever-rising prices, but something about it do to make only a few. It even so that the prices continually rise experts.
While consumers can help themselves, to reduce their electricity bill. Nearly 1,000 power providers compete for customers very easily with a power calculator compare electricity prices. This comparison takes five minutes. However, the potential for savings is enormous. In an average household can save several hundred dollars per year. Previously, consumers had no say in the electricity supplier. Energy could be obtained only through the local utility. Those days are long gone and customers have free choice”.
Unfortunately far too few took advantage of this unique opportunity. Whether E.on, RWE, EnBW and Vattenfall, even the four big energy suppliers have established own daughters of cheap electricity. “” Why so luxury prices “if at a discount price to pay” the same power and own service are available. Because, no matter which provider is selected, there are always the same power from the wall outlet. The service by low-cost carriers is often even better than the power giant by the price war. What makes up the price? The price for electricity is calculated from two parts: the base price (fee) and the labour price (price per kilowatt/hour). Depending on the total consumption also the tariff should be selected. Low consumers often go better with a lower base price. Families, however, consume more, so a lower price and higher base price are good. Comparison of electricity prices must be taken also, whether they appear with or without value added tax. Four steps to the new electricity tariff for the annual electric bill is not always higher, should be considered at immediately reducing our cost base. The way to the new tariff is feasible in only four steps. A look on the last statement of the current year shows the annual total consumption in kilowatt hours (kWh). This consumption value together with the own postcode just enter into a power computer. If you wish further tariff characteristics in the search can or be excluded, only green power, no prepayment, power package, runtime or new customer bonuses. Based on this information, a list will appear with matching electricity suppliers and their tariffs. These prices may be expected in advance maybe even to the current provider. Maybe you can his reach a cheaper tariff, demands is always worthwhile. A matching provider was found through the price calculator, the change goes online quickly and easily. Simply select the desired tariff and the new provider, also annoying denouncing the previous supplier assumes all formalities. Simply fill out the form and sign. The whole process is easier and faster than you might think.
Environmentally friendly energy dwarf in addition to organic certification in the catering area energy efficiency at the Frank Schwarz plays the hypermarket in Duisburg gastro group an important role. Therefore the leading catering company in the region has decided to opt for a mini CHP of the company SenerTec. The costs for electricity and gas screw up to astronomical heights”, so the FAYAZ – Managing Director. With the Dachs’ mentioned system be converted over 95 percent of the fuel energy into usable energy such as electricity and water. The combined production of heat and electricity represents one of the key technologies for energy saving and reducing carbon dioxide emissions.” The operation of such a power plant in miniature format is very simple: In the indoor heat and electricity produced at the same time. This is coupled to a gas-powered internal combustion engine with a generator. The expert speaks of combined heat and power.
How will the waste heat from the engine in a car for heating and the production of warm water used. This is done via so called heat exchanger. A generator powered by the motor produces the electricity. A future-oriented energy investment. For this reason, which has Frank Schwarz gastro group around 35,000 euros invested in the energetic force dwarf. By the power-heat-coupling law have reduced the cost of 5,000 euros, because so much is the State when a new acquisition. The low-interest financing of the total amount was settled about the Sparkasse Duisburg and a KfW loan. I want the Dachs’ around 400 euros saving electricity costs per month. I’m putting all savings on my energy bill, the acquisition has pays after four years.” Information:
For the opposite to the conductors, in these materials it does not have free loads that they can be put into motion with easiness. But the dielectrics also are Constitudos of loaded particles (the electres and the protes). An electric field (external), in the presence of a body insulator, also is modified, even so in different way of what he was a conductor. Let us consider a condenser of plates parallel bars, isolated and loaded with a load Q. Let us full the space enters the plates with an dielectric material, for example, wax, to measure d.d.p now enters the plates of the condenser, we go to see that it diminishes comparing with the situation without wax. However, the stored load does not modify, does not have load movement through the wax layer. Then, the electric field in the condenser diminished due to presence of the wax.
Let us introduce a parameter, called constant dielectric that describes the attenuation of the electric field in the wax layer. Mathematically express in the following way: E= That is, the dielectric constant of a material insulator says how many times weakker are the electric field in this material comparing with the one in the vacuum. As the electric field in the condenser he is homogneo, we can say that the definitive constant through the relation (75) is, of fact, a parameter of the material (in this in case that, of the wax) and does not depend on the geometry or the sizes of the body insulator. Then, the electric field in the material insulator is times weakker of what in the vain emptiness: = This must it the fact of that in a external electric field, the insulator is polarized, that is, appears a induced polarization in the material. Many material insulators are constituted by atoms (or for molecules) that they have not null a dipole moment. As we know, a doublet has trend of to line up itself with the external electric field,
Alternative car drives are on the rise. The car reward this insurer meanwhile also vigorously through properly high discounts, if insured persons buy a vehicle that are equipped with LPG, electricity and gas. The discounts are multi-digit discounts, which today can get actually insured each insurance company today. But this message will still not be penetrated all consumers. While some consumers shy away from also still dealing with the alternative drives LPG, electricity and gas, because they simply do not or not yet trust the technology. However, the low range of the liquefied gas, electricity, and gas-powered holds still other consumers, to purchase such vehicle.
But here too there will be probably changes in the next few years. Certainly one is, that with a charge, autogas, gas and electricity creates 600 miles still far, but especially for little riders it’s worth already today even at the low range today on LPG to switch to electricity and gas. There is also the most manufacturers on the flag written more for their research with respect to methane, have brought in the future to do electricity and gas, the hope that they can drive soon several hundred kilometers may not only among consumers. For the oil industry however, LPG, electricity and gas mean a growing competition. Because if more frequently for the purchase of a vehicle that is operated with LPG, electricity and gas, then this means the consumer to the oil sheikhs of less sales. The plans of car manufacturers and Governments will not enjoy this therefore.
