Why field resistance is greater than the armature resistance in dc mechine
Answer / upenderb
if a dc supply is given to field winding due to inductive effect winding gets shorted and causes damage to the winding So to limit the current high resistance is used.But armature winding has the back emf facility to overcome this drawback
