You are partially right, both methods have drooping curves, actually fine control reflects the slope of the torque speed curve, if u have a flatter curve it means u have fine control ( less speed variation with induced torque ), the resistance control has a very steep curve, so it has huge variation in speed with variation in torque induced which is not very good for practical use...
yeah you are correct...actually i thought you were asking to compare arm voltage control and arm resistance control ( sorry for that ), It would not be correct to compare field control and resistance control bcz both are used for different speed ranges ( field control - above base speed and Arm resistance control - less than base speed), but you can have a comparison between arm voltage control and arm resistance control bcz both are used for speed control less than base speed, In that case clearly arm voltage control doesnt change the slope and you get a finer speed control, sorry for the earlier reply.....thank you hope it clears
Thanks a lot sir ur teaching skills are awesome, and a very very thank you for making such kind of amazing video
Thank you for making video on this lecture which help us a lot
In field current control the slope also changes thus it means we are losing fine speed control there also.Correct me if I am wrong

varun nair but in both the cases the slope changes by the same amount (mathematically) isn't it?

Thank you sir
Clear my concept which I got dust in past
+akshay kumar thank you very much....glad to be of help
"Aiya! I forgot something here"😂😂
Can you tell the timestamp..let me also listen to that...
Check 2:20
Btw i was just joking 🙂
Your videos saved me😇
Thanks a lot❤
Just checked it out. It was funny
