• "By power level: from a fraction of a volt-ampere (VA) to over a thousand MVA;"
• "The closer the power supply comes to delivering the rate amplifier, don't need to drill holes ideal power factor of 1 (where 1 volt-ampere produces 1 watt), the more efficient the power supply will be and in your walls, and don't need to snake the less strain it will place on your PC's wiring."
• "Getting a true power - as opposed to a volt-ampere reading basically requires multiplying the voltage and current waveforms instant-by-instant and integrating the product over the period of one cycle."
