    Sir at 9:18 after that point why emf generation is stopped sir

    Sir at 4:31 you already made supply off. Only residual flux is present ,then how you took Eg /R sir How Eg is produced .

      Dear brother....yes after Supply is turned off...there is a some flux called Residual flux....and kindly notice that...the generator is still rotating....so when the rotating Armature cuts that the residual flux an emf Induced so that... induced emf posses current...that current also posses flux so togetherly this flux and residual flux will again build up the flux again the emf increased...that's process goes on increasing till the Respective field resistance stops the Building up of emf........is this clear to you Mr.Bharath sai..!?

    A DC shunt generator build up its rated voltage.if the direction of rotation, field terminals and residual magnetism are reversed.then what will be the generated voltage sir??

      Sir ,as generated emf is proportional to flux and speed.here both flux and rotation is reversed .
      So emf proportional to (-flux)*(-speed),which is generator build its voltage with same polarity.
      Is this method correct sir??

    sir what is mean by retentivity property ,what happens if the retentivity property increases

  • @karthikeya2466

    Sir why if shunt generator is excited on open circuit its field resistance should be less than critical field resistance

    Sir in separately exited generator in field indicates E1 E2 ga sir

    Respected sir.. One humble suggestion.. If colours such as green and red are used it becomes more clear.. Especially in graphs.. Thank you sir

    Sir ur teaching process is truly amazing and i feel the most important part of ur lectures are the small summarising in between the videos..
    Thanks and regards Sir

    Sir many many thanks for ur such knowledge. sir i hade doubt in critical resistance since from my class but now because of ur lectures i really understand .. what's..
