The switching speed will be increased because of more current drawn by relay

The switching capacity of the relay will be decreased very strongly

The relay draws more current in the absence of inductive reactance, which bruns out the coil

D.C. operation causes the core and armature to become partly permanent magnet and fails to function after a few operations

in closed condition in all the status of relay

open when the relay coil is de-energised

open when the relay coil is energised

closed when the relay coil is energised
