Transformers work by induction. A changing magnetic field is required.
A dc series motor can work on dc and ac because dc motors are totally reversible.
Transformers don't work with DC supplies - they only work on AC.
Yes, if the fan is designed to work on DC voltage, otherwise no.
No, unless you have a pulsating DC
they work in Washington DC
Well, yes. But it isn't much needed as DC is already DC.
it creates a dc current
it is only work on it so that used
Yes.
An inductor cannot work in dc because the frequency is zero there by making the inductive reactance zero as a consequenceAnswerOf course an inductor can work in a d.c. circuit!
No it cant
transformer cannot be worked on DC because as the dc is constant there will be no change of flux & may lead to shot circuit.
