In the figure shown, a circuit contains two identical resistors with resistance \(R = 5\,\Omega \) and an inductance with \(L = 2\, mH\). An ideal battery of \(15\, V\) is connected in the circuit. What will be the current through the battery long after the switch is closed?......\(A\)

Pick an option to check your answer.
Answer & Solution
Correct Answer
(D) \(6\)
Step-by-step Solution
Detailed explanation
After long time, inductor will behave like resistance less wire,
\(\mathrm{i}=\frac{15}{\mathrm{R}_{\mathrm{m}}}=\frac{15}{(5 / 2)}\)
\(=6 \,\mathrm{A}\)
