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.
Wiedemann-Franz law: It is the ratio of the thermal conductivity of any pure metal (substance) to its electrical conductivity is just about constant for any specified temperature. This law holds pretty well apart from at low temperatures.

Paschen series: The series that explains the emission spectrum of hydrogen whenever the electron is jumping to the third orbital. Each and every line is in the infrared part of the spectrum.
Hawking temperature: The temperature of a black hole is caused by the emission of the hawking radiation. For a black hole with mass m, it is illustrated as: T = (hbar c3)/(8 pi G k m).
