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.
The answer is the option (b)
D2 is forward biased and D1 is reverse biased and hence no current flows from B to A and vice versa.
