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. WebJun 3, 2005 · Keep in mind that heat is the real problem that will kill the transformer -- so fans can be helpful in squeezing a bit more power out of a transformer beyond it's actual nameplate rating. Similarly, if you have the transformer stuffed into a 120-degree electrical room, you may find that nameplate IS an overload condition. . . .
