A zener diode with 5 V zener voltage is used to regulate an unregulated dc voltage input of 25 V . For a 400Ω resistor connected in series, the zener current is found to be 4 times load current. The load current (IL) and load resistance (RL) are :

[2 Apr 2025 Shift 1]

IL=20‌mA;RL=250Ω
IL=0.02‌mA;RL=250Ω
IL=10‌mA; RL=500Ω
IL=10A;RL=0.5Ω
