Armature reaction is magnetizing in nature due to a purely resistive load in the synchronous generator.

Armature reaction is magnetizing in nature due to a purely resistive load in the synchronous generator. Correct Answer False

Due to a purely resistive load, armature current is in quadrature with the field magneto-motive force. Armature magneto-motive force produced due to this current will be in quadrature with the field flux. It will try to increase the net magnetic field.
