Question: In the following circuit of PN junction diodes $ D _{1} $ , $ D _{2} $ and $ D _{3} $ are ideal then I is
Options:
A) $ E/R $
B) $ E/2R $
C) $ 2E/3R $
D) Zero
Show Answer
Answer:
Correct Answer: A
Solution:
[a] Diodes $ D _{1} $ and $ D _{3} $ are forward biased and $ D _{2} $ is reverse biased so the circuit can be redrawn as follows.
