    I will be moving to Argentina, 220 V 50 hz. Will a simple diode of correct Amp rating in series reduce power and allow the use of my kitchen cooking utensles? How about simple power tools like a drill or saw?

    Incorrect and untested methods will result in electrical hazards. Use a transformer (step up or step down whichever is applicable) of appropriate rating between the power supply and your appliance. This looks like a test bench experiment. Although your idea is theoretically possible, in reality it involves risks and poses safety issue as per electrical codes. :eek:

    Plz take guidance from trained professionals before venturing into uncharted territory! :)

    Gud luck,

    yes 220v 50 hz and you have 120v 60hz tools you may add a resistance of equal value of the motor to operate it. Now consider this it would be like two tools operating at the same time efficiency 50%. You may try a transformer to reduce the 220 to 120v but do not buy it here for 50 hz you will need more iron for the 10 hz difference buy it there in argentina. again EFFICIENCY will drop possibly 25 or more %. the conclusion is if it is a 2 watts no big deal but 1000w aircond. waste of money big time. you may ask the power company to bring in a nuetral wire for 120v or buy 220v 1000w aircond that will be smart and more efficient. power is money.
