WebMar 26, 2016 · Remember the basic formula for calculating electric power: P = V I. In other words, power equals voltage times current. A transformer transfers power from the primary coil to the secondary coil. Since the power must stay the same, if the voltage increases, the current must decrease. Likewise, if the voltage decreases, the current must increase. WebFeb 27, 2024 · Transformers core sizes are closely matched to the operating voltage. Little increase over the design voltage is needed to saturate a transformer, which will result in an orders of magnitude increase in current being drawn. In the best case, this will take out …
