In the given circuit switch is closed. In steady state the current will be :

2 A 27 A 6 A 0.67 A

6 A

In Steady state the inductor is short circuited hence no potential difference across inductor. In this situation all the three resistors are in parallel. $\Rightarrow R_{eq} = \frac{R}{3} = 3\Omega$ $\Rightarrow I = \frac{\xi}{3} = \frac{18}{3} = 6A$
