In Fig. 14.2, assuming the diodes to be ideal, (a) D1 is forward biased and D2 is reverse biased and hence current flows from A to B (b) D2 is forward biased and D1 is reverse biased and hence no current flows from B to A and vice versa. (c) D1and D2 are both forward biased and hence current flows from A to B. (d) D1 and D2 are both reverse biased and hence no current flows from A to B and vice versa.

In Fig. 14.2, assuming the diodes to be ideal, (a) D1 is forward bias

1.	In Fig. 14.2, assuming the diodes to be ideal, (a) D1 is forward biased and D2 is reverse biased and hence current flows from A to B (b) D2 is forward biased and D1 is reverse biased and hence no current flows from B to A and vice versa. (c) D1and D2 are both forward biased and hence current flows from A to B. (d) D1 and D2 are both reverse biased and hence no current flows from A to B and vice versa.
Answer» (b) D₂ is forward biased and D₁ is reverse biased and hence no current flows from B to A and vice versa.
