Q29.A 8V Zener diode along with a series resistance ๐ is connected across a 20 V supply (as shown in the figure). If the maximum Zener current is 25 mA, then the minimum value of ๐ will be _____ ฮฉ.
What This Question Tests
This question tests the understanding of a Zener diode's operation in a voltage regulator circuit, applying Ohm's law to find the series resistance.
Concepts Tested
Formulas Used
V_R = V_supply - V_Zener
R = V_R / I_Zener_max
