Ampere - Tomax7.com
Volt-ampere (VA) is a measurement of power in a VA. This does not mean it can deliver 600 watts, unless the equipment is reactance-free. In real life, the true wattage rating of a power supply is 1/2 to 2/3 A transformer is an electrical device that takes electricity of one voltage and ... Access Document
