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.

Gray: Gy (after L.H. Gray, 1905-1965): The derived SI unit of engrossed dose, stated as the absorbed dose in which the energy per unit mass communicated to the matter by the ionizing radiation is 1 J/kg; it therefore has units of J/kg
A dual-wavelength spectrometer uses 780 nm and 830 nm. The molar extinction coefficients for oxy-hemoglobin (HbO2) and deoxy-hemoglobin (Hb) at these two wavelengths are: e_HbO2_780nm = 710 cm-1M-1, e_Hb_780nm = 1075 cm
