What are the conditions to be fulfilled by for a dc shunt generator to build back emf?
Last Answer : The generator should have residual flux, the field winding should be connected in such a manner that the flux setup by field in same direction as residual flux, the field resistance should be less than critical field resistance, load circuit resistance should be above critical resistance. ...
Is it possible to include/ Exclude external resistance in the rotor of a Squirrel cage induction motor?. Justify
Last Answer : No it is not possible to include/ Exclude external resistance in the rotor of a Squirrel cage induction motor because, the rotors bars are permanently short circuited by means of circuiting rings (end rings) at both the ends. i.e. no slip rings to do so....
