In the figure, assuming the diodes to be ideal:
- A \( D_2 \) is forward biased and \( D_1 \) is reverse biased and hence no current flows from B to A and vice-versa
- B \( D_1 \) is forward biased and \( D_2 \) is reverse biased and hence current flows from A to B
- C \( D_1 \) and \( D_2 \) are both forward biased and hence current flows from A to B
- D \( D_1 \) and \( D_2 \) are both reverse biased and hence no current flows from A to B and vice-versa
Answer & Solution
Correct Answer
(A) \( D_2 \) is forward biased and \( D_1 \) is reverse biased and hence no current flows from B to A and vice-versa
Step-by-step Solution
Detailed explanation
Identify the Potential Difference Current naturally tends to flow from a higher potential to a lower potential. In this circuit, point \(B ( 0 ~ V )\) is at a higher potential than point \(A (- 1 5 ~ V )\). Therefore, the "intended" direction of current is from \(B\) towards…
