Answer / percy

yes there is a difference in current carrying capacity as
dc current spreads in whole conductor area and the ac
current density is not uniform and hence the resistance in
ac will be high in case of AC

In synchronous motor, how the field current is related to armature current..i know its inversely proportional..but concept wise...i was nt clear....pls help me...
