MCQ
In the circuit shown in figure
  • A
    In steady state, there is no current in the $100\,\Omega$ resistor
  • ✓
    In steady state, the current in  $100\,\Omega$ resistor is $0.08\, A$
  • C
    In steady state, there is no current in the  $50\,\Omega$ resistor
  • D
    In steady state, the current in  $50\,\Omega$ resistor is $0.04\, A$
✓

Answer

Correct option: B.
In steady state, the current in  $100\,\Omega$ resistor is $0.08\, A$
b
In steady state no current will flow through the capacitor.

$\therefore $ $I=\frac{12}{100+50}=\frac{12}{150}=0.08 \mathrm{\,A}$
