Montezuma, Moctezuma, Moteczoma, Motecuhzoma, Moteuczomah, and Mwatazuma are variant spellings of the same word and may refer to:
Voltage, Frequency and Plug/Outlet Type in United States of America / USA. Electricity in United States of America / USA is 120 Volts, alternating at 60 cycles per second. If you travel to United States of America / USA with a device that does not accept 120 Volts at 60 Hertz, you will need a voltage converter.
Peak voltage of a perfect sine wave is 1.414 times RMS, so our 120 VAC mains (without harmonics or clipping) crest at 169.68 volts peak. If we rectified the power line and filtered the DC with a perfect capacitor input supply, like most conventional and switch mode supplies do, we would have about 170 volts DC.
