Figure shows a circuit contains three identical resistors with resistance \[R=9.0\,\,\Omega \] each, two identical inductors with inductance \[L=2.0\text{ }mH\] each, and an ideal battery with emf \[\varepsilon =18\,V\]. The current \['i'\] through the battery just after the switch closed is [NEET-2017] |
A) 0 ampere
B) 2 mA
C) 0.2 A
D) 2 A
Correct Answer: D
Solution :
[d] |
At \[t=0,\] no current flows through \[{{R}_{1}}\] and \[{{R}_{3}}\] |
\[i=\frac{\varepsilon }{{{R}_{2}}}\] |
\[i=\frac{\varepsilon }{{{R}_{2}}}\] |
\[=2A\] |
