Basically, this device allows you to increase or decrease the voltage and intensity of an electric current (alternating), but keeping the power constant. " - How do voltage transformers work

How do voltage transformers work

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. WebFeb 24, 2012 · The transformer can transfer energy in both directions, from HV to LV side as well as inversely. That is the reason why it can work as a voltage step-up or step down transformer. Both transformer types have …
