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.
