Assuming the diodes to be of silicon with forward resistance zero,...

Assuming the diodes to be of silicon with forward resistance zero, the current I in the following circuit is39. Assuming the diodes to be of silicon with forward resistance zero, the current I in the following circuit is Assuming the diodes to be of silicon with forward resistance zero, the current I in the following circuit is39.

Options

  1. A0
  2. B9.65mA9.65 \mathrm{ mA}
  3. C10mA10 \mathrm{ mA}
  4. D10.35mA10.35 \mathrm{ mA}

Correct answer

C. 10mA10 \mathrm{ mA}

Step-by-step solution

I=VR=202×103=10×10−3A=10mAI=\frac{V}{R}=\frac{20}{2 \times 10^{3}}=10 \times 10^{-3} \mathrm{ A}=10 \mathrm{ mA}
