Question:
In the figure, 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) D1 and 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
Solution:
(b) D2 is forward biased and D1 is reverse biased and hence no current flows from B to A and vice versa
