MCQ
In the circuit (Fig), the final current through $30\, \Omega $ resistance when circuit is completed is.........$A$
  • A
    $3$
  • $0.1$
  • C
    $5$
  • D
    $0.5$

Answer

Correct option: B.
$0.1$
b
The current is short circuited through inductor. In stready state, current will pass through inductor instead of $20\, \Omega$

Then current through $30\, \Omega$ is:

$\mathrm{I}=\frac{3}{30}=0.1 \mathrm{\,A}$
