JEE PYQ: Semiconductors Question 15
Question 15 - 2021 (26 Feb 2021 Shift 2)
The zener diode has a $V_z = 30$ V. The current passing through the diode for the following circuit is ______ mA.
Show Answer
Answer: 9
Solution
$I = (90 - 30)/(4 \times 10^3) = 15$ mA. $I_L = 30/(5 \times 10^3) = 6$ mA. $I_z = 15 - 6 = 9$ mA.
