Power Generators
Power generators are devices that will create electricity in the event that electricity is not available. Although, these are usually considered to be personal types that create the electricity that a home would need if the main power goes out. These will power refrigerators and freezers in order to keep food from spoiling or to keep a furnace running to keep the cold out. But, how do these work? How exactly does a generator create electricity? Lets explore this and attempt to explain exactly how this works.
The principle that creates this electricity was invented by Michael Faraday in eighteen thirty one and is called induction. What is induction? Induction is what happens when a conductor, such as a copper wire, is moved in a magnetic field. When this movement is done, it creates an electrical current to flow inside the wire. This process is, as mentioned earlier, is referred to as induction. But, it goes farther than that, there are two forces that work together to create this. They are the mechanical force that it takes to move the conductor and the electrical current that is created while moving the conductor in the magnetic field. This is how our electricity that powers our homes is created. Although, a majority of it is created hydrostatically, it still requires some mechanical aspect or force in order to generate the electricity. In this case, it is the water that flows from a flowing source and over a turbine, forcing the turbine to spin that is the mechanical requirement. This is how most hydro or water based electricity companies work.
Of course, those are the extremely large type generators that create millions of watts a day. There are the portable type that creates electricity exactly the same way, except that they generate much smaller amounts of wattage. There is one major difference though, these run by an internal combustion engine. These engines must have a fuel source much like the water creating the fuel source for the hydro version. Therefore, the fuel that causes the mechanical aspect is either gasoline or diesel fuel. These run much like any small engine however, instead of mowing or lawn, or weed eating it, it is creating electricity.
Back to say, powering the refrigerator. Depending upon the wattage requirements for one's specific type of refrigerator, this will depend on the size or output of the power generator. Basically, the higher the wattage requirement, the larger the power generator. Therefore, always consider the amount of power that you will need at peak periods during a catastrophic event and buy one accordingly. Keep in mind that one will only want to power a certain number of devices during such a problem, so,, be sure to get one that fits your specific needs.
