JEE PYQ: Semiconductors Question 44
Question 44 - 2019 (11 Jan 2019 Shift 2)
The circuit shown below contains two ideal diodes, each with a forward resistance of $50\ \Omega$. If the battery voltage is 6 V, the current through the $100\ \Omega$ resistance (in Amperes) is:
(1) 0.036
(2) 0.020
(3) 0.027
(4) 0.030
Show Answer
Answer: (2)
Solution
$D_2$ is reverse biased. $R_{eq} = 150 + 50 + 100 = 300\ \Omega$. $I = 6/300 = 0.02$ A.
