Figure shows a circuit contains three identical resistors with resistance\[R=9.0\,\Omega \]each, two identical inductors with inductance L = 2.0 mH each, and an ideal battery with emf \[\varepsilon =18\,V.\] The current 'i' through the battery just after the switch closed is
A) 0 ampere
B) 2 mA
C) 0.2 A
D) 2 A
Correct Answer:
D
Solution :
At t = 0, no current flows through \[{{R}_{1}}\]and\[{{R}_{3}}\] \[i=\frac{\varepsilon }{{{R}_{2}}}\] \[=\frac{18}{9}\] \[=2A\] Note: Not correctly framed but the best option out of given is [d].
