Question

What will be current through the $200\Omega$ resistor in the given circuit a long time after the switch ‘K’ is made on ?

• A. Zero
• B. 100 mA
• C. 10 mA
• D. 1 mA

Answer 1

Answer: (C)

In steady state, arm having capacitors does not flow current. So, we can neglect them
$\therefore$ The given circuit reduce to

$\therefore R_{net}=200+400=600\Omega$
$\therefore$ Current in circuit,
$I=\frac{V}{R}=\frac{6}{600}=0.01A$
$=10mA$
