12. The figure shows a circuit that contains three identical resistors with resistance R=9.0Ω, two identical inductors with inductance L=4.0 mH, and an ideal battery with emf ξ=36 V. IA is the current just after the switch is closed, and IB is the current through the battery long after the switch has been closed. What is the current ratio IA/IB?
(A) 1/3
(B) 1/2
(C) 1
(D) 2
(E) 3
