Calculate the charge on capacitor in steady state.

Calculate the charge on capacitor in steady state.

Options

  1. A50μC50 \mu \mathrm{C}
  2. B30μC30 \mu \mathrm{C}
  3. C45μC45 \mu \mathrm{C}
  4. D60μC60 \mu \mathrm{C}

Correct answer

C. 45μC45 \mu \mathrm{C}

Step-by-step solution

 In steady state, i=927×103Vc=I×R=927×103×15×103=5Vq=CVc=9×10−6×5q=45×10−6C=45μC\begin{aligned} & \text{ In steady state, } i=\frac{9}{27 \times 10^3} \\ & V_c=I \times R=\frac{9}{27 \times 10^3} \times 15 \times 10^3=5 \mathrm{ V} \\ & q=C V_c=9 \times 10^{-6} \times 5 \\ & q=45 \times 10^{-6} \mathrm{C}=45 \mu \mathrm{C}\end{aligned}
