Semiconducting Devices Question 49
Question: The circuit shown in following figure contains two diode D1 and D2 each with a forward resistance of 50 ohms and with infinite backward resistance. If the battery voltage is 6 V, the current through the 100 ohm resistance (in amperes) is
[IIT-JEE 1997]
Options:
A) Zero
B) 0.02
C) 0.03
D) 0.036
Show Answer
Answer:
Correct Answer: B
Solution:
According to the given polarity, diode D1 is forward biased while D2 is reverse biased.
Hence current will pass through D1 only.
So current $ i=\frac{6}{(150+50+100)}=0.02A $
