How many volts in a transformer
WebVolt-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 . Web22 aug. 2014 · That "VA" refers to volts * amps, so using the 12V output alone it's roughly (7.5VA / 12) .625 amps. Your transistor selection doesn't really depend on the output of the transformer, however, but rather the current consumption of the light or motor that the individual transistor will be switching power to. system August 21, 2014, 11:22pm #3.
