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
- B 0.2 A
- C 0.1 A
- D 0.25 A
Answer & Solution
Correct Answer
(B) 0.2 A
Step-by-step Solution
Detailed explanation
Since it is reversed based diode so it will work as open wire \(\mathrm{i}=\frac{2}{10}=0.2 \mathrm{~A}\)
