Q30.In a given circuit diagram, a 5 V zener diode along with a series resistance is connected across a 50 V power supply. The minimum value of the resistance required, if the maximum zener current is 90 mA will be Ω.
What This Question Tests
This question requires calculating the series resistance needed for a zener diode voltage regulator, considering the maximum zener current.
Concepts Tested
Formulas Used
R_series = (V_supply - V_zener) / I_total
I_total = I_zener_max + I_load
