A) zero
B) 36 mA
C) 43 mA
D) 50 mA
Correct Answer: B
Solution :
According to the given polarity, diode \[{{D}_{1}}\] and \[{{D}_{2}}\] are forward biased while \[{{D}_{3}}\] is revers biased. Hence current will pass through \[{{D}_{1}}\] and \[{{D}_{2}}\]only. Total restiance in drcuit. \[R=\frac{100\times 200}{200+100}+100\] \[R=\frac{200}{3}+100=\frac{500}{3}\] \[\therefore \] Current, \[i=\frac{6}{\frac{500}{3}}=\frac{18}{500}=36\times {{10}^{-3}}\] = 36 mAYou need to login to perform this action.
