I have a question- If a transformer can increase volts, are ampers also increased, or are they decreased. Because if they are increased as well, isn't a transformer getting energy from nothing? | ||

Watts are the product of volts and amps. In a transformer, the total output wattage is always lower than the total input, due to heat losses. If the transformer increases the voltage, the amps go down proportionately. | ||

So wattage is lost due to heat losses? Would it be the same for an alternating current, since there is less heat losses? | ||

The heat losses are due to the current in the transformer. AC or DC will not matter if the currents are the same. |
