1. Almost all of them actually generate 3-phase AC

   The large ones then go through transformers and in some cases feed the national grid.

   Smaller private ones usually get rectified (diodes used to convert AC to DC) and are used to charge batteries.

2. it could do either…most likely AC due to transmission losses.

3. The turbine doesn’t generate anything. It just spins. Turbines can be spun by gasses, steam, water, wind, etc….

   The GENERATOR connected to the turbine, determines what type of electricity is produced.

4. AC. It has to do with electromagnetism, and the manner in which the copper wire is wound inside the generator.

5. It generates direct current, which is DC.

   Only a power plant can generate alternating current.

6. both but without the rectifier it will generate an ac current but with a rectifier it will generate a dc current

   (the ampage and voltage level of the turbine will depend on how fast it is spinning)

   wind turbines are basically just wind pushed alternators and obvousivly alternators genorate ac currents so that expalins alot
   so in ordor to straiten everything out (you can’t do much with an ac current) you’ll neeed a rectifier

7. Unless it is an older type generator with brushes and a commutator, most all rotary alternators/generators produce AC sine wave voltage – if DC is required, it is rectified either externally or internally with extra circuitry.
   When DC is required, the alternators usually have three separate windings, producing three phase AC, which provides a much smoother DC when rectified.
   When the alternators speed is regulated to 3600 RPMs and 120 volts, the common household 60 Hz AC voltage is produced.

8. The typical wind turbine spins an AC generator for transmission onto the electrical grid. This is why it has adjustable blade pitches etc – it must stay synchronous to the AC 3-phase grid (60Hz).

   This is in respect to large industrial turbines, not sure about the little ones by the ponds on farms.
