The mechanical power developed by the armature of a d.c. motor is equal to?
The mechanical power developed by the armature of a d.c. motor is equal to armature current multiplied by back e.m.f.
Answer : The mechanical power developed by a shunt motor will be maximum when the ratio of back e.m.f. to applied voltage is 0.5. ...
