JEE Main 2024 — Semiconductors Question with Solution

JEE Main 2024 (30 Jan Shift 1)

Question

A Zener diode of breakdown voltage 10 V is used as a voltage regulator as shown in the figure. The current through the Zener diode is

Show full solutionCorrect option: C
Correct answer
C30 mA

Step-by-step explanation

As Zener is in breakdown region, therefore potential drop across it would be 10 V. Now, 

I3=10500=150 A and 

I1=10200=120 A

Also, I2=I1-I3

⇒I2=120-150=3100 A=30 mA
