Drive the generator! Generally to avoid damage to the generator (excessive wind), there will be a brake in front! However, the actual circuit is more complicated. The circuit is also connected to AC and converter etc. !
Electrical energy is stored in capacitors! Or send it directly to electrical devices!
The conversion of mechanical energy into electrical energy is the principle of a generator, that is to say that part of the conductor in a closed circuit moves in the magnetic field to cut the lines magnetic field! There will be a circuit in the circuit, which is generally called induced current in order to distinguish it! This phenomenon is called electromagnetic induction! This is a phenomenon and generally does not require explanation! Just like the difference between invention and discovery!
