Transformers do not actually make conversion between mechanical and electrical form, but they transfer electric power from one circuit to another circuit. They can decrease or increase the voltage while transferring the power without changing the frequency, but with the corresponding increase or decrease in the current. Transformers also belong to electrical machines.
Just like generators, motors also consists two basic parts, stator and rotor. In a motor, we give electric supply to both the stator and rotor windings which causes a mechanical force between the stator and rotor. This force causes the rotor to rotate.
Vehicle identification numbers are a crucial tool for police force agencies within their efforts for preventing car theft and hijacking, searching for car thieves and helping consumers avoid buying stolen vehicles. Since a lot of used vehicles on the market nowadays have been previously stolen, doing a VIN check is essential when selecting a second hand vehicle. The most reliable opportinity for ensuring that you will find the correct VIN is obtaining it completely from the vehicle, instead of the car's title, because the number entirely on that document might not be written down correctly.
Some algae species are 50% or maybe more lipid oil by weight. This oil can be pressed in the algae and refined into diesel. The process for extracting algal oil, at its most elementary level, is similar to pressing an olive. Up to 75% with the oil could be squeezed from algae which has a simple mechanical press. Hexane may be used as a solvent to increase extraction as much as 95%. Once extracted, the oil is refined through transesterification. A catalyst including sodium hydroxide is when combined alcohol to create biodiesel and glycerol.
