ElectroMagnetic InductionHard
Question
The circuit shown in figure is allowed to reach steady state and then a soft iron core is inserted in the coil such that its coefficient of self inductance changes from L to nL. The steady current in the circuit after complete insertion is
Options
A.
B.
C.
D.Zero
Solution
In steady state, inductor will behave as shortcircuit so i =
