q4 b
(B)-ndicate whether the following statements are true or false and correct the faise statements. -When a series d.c. motor is operate without load, the armature will not run. The strength of magnetic field in d.c. shunt generator can be varied by varying the polarity of the field poles The main disadvantage of series generators is Output voltage varies as the Toad varies There is no output from the transformer under short-circuit conditions
