Do transformers obey Ohm's law?

Best Answers

This is baloney – a transformer is nothing more than a pair of inductors, which are perfectly ohmic (ie. they obey Ohm’s law). For our purposes, an inductor can be thought of as a resistor that only resists AC current (this sort of “resistance” is called impedance). read more

Yes Ohm’s law applies to transformers and any load connected to them. The windings have resistance so there will be losses which obey Ohm’s law. The transformer and the load you connect to a transformer will have some reactance which may need to be taken into account. There will be some core losses. read more

Firtly, I am assuming that transformers do follow ohm's law (v=ir). Now my question is regarding why step up transformers reduce current. For according to ohm's law, the increase of voltage directly results in a increase in current assuming constant resistance. read more
