A 2 V cell is connected across to points A and B as shown in the figure. Assume that the resistance of each diode is zero in forward bias and infinity in reverse bias. The current supplied by the cell is

• A

  0.5 A
• Correct answer
  B

  0.2 A
• C

  0.1 A
• D

  0.25 A

Solution

Since it is reversed based diode so it will work as open wire
$\mathrm{i}=\frac{2}{10}=0.2 \mathrm{~A}$

Hence, the correct answer is option: 'B'.
