QJEEM21Ph337c: JEE Main 2021 Physics - Class 12 JEEM21Ph337c Solution: The zener diode has a V z = 30V. The current passing through…

The zener diode has a V_z = 30V. The current passing through the diode for the following circuit is ________ mA.

Step-by-Step Verified Solution

$I = {{90 - 30} \over 4} = 15mA$

${I_1} = {{30} \over {5K\Omega }} = 6mA$

${I_2} = 15mA - 6mA = 9mA$
