Why DC Currents are not used in transformer?

Answer Posted / jaheerabbas

in transformer primary and secondary windings are behaves
like inductor in initial stage (t=0)sec, inductor impedance
formula is 2*pi*F*L, so F=0 means DC then no inductor
effect,no inductor effect then no Flux,no EMF nothing....so
only we are not using DC signal in transformer

Is This Answer Correct ?    2 Yes 0 No
