    Alternating current (AC) electricity moves in a sine wave, alternating between positive and negative poles. AC frequency, expressed as hertz (Hz) refers to the number of times per second completes a full cycle between these positive and negative poles. A byproduct of these cycles is heat.

    Voltage converters and voltage transformers do basically the same job. They allow appliances and electronic devices to be used in countries where the voltage supplied by the wall outlet is different from the voltage for which the appliance was built. But they accomplish this in different ways. Alternating current (AC) electricity is
