JEE PYQ: Semiconductors Question 42
Question 42 - 2019 (10 Jan 2019 Shift 2)
For the circuit shown below, the current through the Zener diode is:
(1) 9 mA
(2) 5 mA
(3) Zero
(4) 14 mA
Show Answer
Answer: (1)
Solution
$I_{5k\Omega} = 70/5000 = 14$ mA. $I_{10k\Omega} = 50/10000 = 5$ mA. $I_{zener} = 14 - 5 = 9$ mA.
