What is the correct order for how wind generators work?
Wind blows, it goes into the transformer, then it turns a turbine, the turbine makes the generator work, then it travels to your house.
Wind blows, it turns a turbine, the turbine causes the generator to make electricity, electricity flows to the transformer where it is intensified, and then it travels through power lines to your house.
