WebbVolt-ampere (VA) is a measurement of power in a direct current ( DC ) electrical circuit. The VA specification is also used in alternating current ( AC ) circuits, but it is less precise in this application, because it represents apparent power , which often differs from true power . WebbAnswer (1 of 7): Trying to feed 120V AC to a device that can only take 25V DC, is a fire work waiting to happen, as the current drawn will be 5 times higher - you cannot control the current draw. Unless you use a current limiter circuit and limit it to max 2.5A. Then the voltage will drop, becau...
