Question

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 1

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