In a very hot summer period, a electromechanical technician decided to install a air conditioner in your home. To the note that the power pattern was single-phase, with 127V voltage, and that the air conditioners commercially available were 220V, the technician realized that: Answer: The step-up transformer to obtain 220V from a 127V socket should have a transformation ratio equal to 0.57.
