WebFeb 24, 2012 · A step-down transformer is a type of transformer that converts the high voltage (HV) and low current from the primary side of the transformer to the low voltage (LV) and high current value on the … WebStep up transformers change a low voltage/high current, to high voltage/low current. So, in an ideal 100% efficient transformer, the power doesn't change and no heat will be generated by the transformer, i.e. the power in = the power out, because Power = Volts x Amps. Aha, that makes sense. danny\u0027s auto sales grafton wi https://daria-b.com
