Options
- A. D_1 is forward biased, D_2 is reverse biased
- B. D_1 is reverse biased, D_2 is forward biased
- C. D_1 and D_2 both are forward biased
- D. D_1 and D_2 both are reverse biased
Answer
B. D_1 is reverse biased, D_2 is forward biased
Step-by-step solution
aligned & At t =15 msec \\ & V _ in =220 (100 15 10^ -3 ) \\ & =220 ( 3 2 )=-220 ~V aligned So diode D_1 is in reverse bias and D_2 is in forward bias
