The contribution to output voltage from diode 2 is
A) A, C
B) B, D
C) B, C
D) A, D
Correct Answer: B
Solution :
[b] In the positive half cycle of input ac signal diode \[{{D}_{1}}\] is forward biased and \[{{D}_{2}}\] is reverse biased so in the output voltage signal, A and C are due to \[{{D}_{1}}\]. In negative half cycle of Input ac signal \[{{D}_{2}}\] conducts, hence output signals B and D are due to \[{{D}_{2}}\].
