Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

thank u
![eduncle-logo-app]()
iam confused with case 2, that is at t=infinity how i becomes 1/10.now all my doubt will be cleared
![eduncle-logo-app]()
at t= infinity all current will pass through inductor , no current will pass through r=10 ohm
![eduncle-logo-app]()
so following the path of inductor the resistance in that path is 20 ohm so I=V/R that is 2/20

this will help u dear for querry plz asl
ask*
mam, at t=infinity why, u wont consider 10 ohm resister
is there is no need to consider 10 ohm resister
