ElectroMagnetic InductionHard
Question
In the LR circuit shown, what is the variation of the current I as a function of time ? The switch is closed at time t = 0 sec.
Options
A.
B.
C.-
D.None
Solution
In loop CDEF current is independent of the time as current will remain 
all the time
∴ Circuit equivalent can be considered as current at any time =
By super imposing the two current the net current in it will be
i =
all the time∴ Circuit equivalent can be considered as current at any time =
By super imposing the two current the net current in it will be
i =
