How energy transformed in windmills
Explain how is energy transformed in the windmills?
Expert
Basically what happens is that as the energy from the wind rotates the vanes of mill, coils of wire rotate within a permanent magnet (or generator) and generate electric voltage or current. This current is then sent to the grid and used by us as the electricity which is another form of energy. This is a much simple description and there is a lot more in the design of the system.

Define Ideal gas constant or universal molar gas constant?
Ideal gas constant: or universal molar gas constant; R: The constant which appears in the ideal gas equation. It is equivalent to

Kilogram: kg: The basic SI unit of mass that is the only SI unit still maintained by a physical artifact: a platinum-iridium bar reserved in the International Bureau of Weights and Measures at Sevres, France.
For the magnetically coupled circuit in Figure a, calculate I_{1} and I_{2}. If the dotted terminals in are changed so that the circuit now becomes that in Figure b, re-calculate I_{1} and I_{2}.
Avogadro's hypothesis (Count A. Avogadro; 1811): Equivalent volumes of all gases at similar temperature and pressure contain equivalent numbers of molecules. This is, in fact, true only for the ideal gases.
