JEE PYQ: Semiconductors Question 14
Question 14 - 2021 (26 Feb 2021 Shift 1)
The circuit contains two diodes each with a forward resistance of $50\ \Omega$ and with infinite reverse resistance. If the battery voltage is 6 V, the current through the $120\ \Omega$ resistance is ______ mA.
Show Answer
Answer: 20
Solution
$D_2$ is reverse biased (no current). $D_1$ forward biased: total resistance $= 50 + 130 + 120 = 300\ \Omega$. $I = 6/300 = 0.02$ A $= 20$ mA.
