The zener diode in the circuit has a zener voltage of 5.8V and knee current of 0.5mA. The maximum load current drawn with proper function over input voltage range between 20 and 30V is?(a) 23.7mA(b) 20mA(c) 26mA(d) 48.3mAI have been asked this question in an online quiz.My question comes from Breakdown Diodes topic in section Semiconductor-Diode Characteristics of Electronic Devices & Circuits

Answer»

Correct OPTION is (a) 23.7mA

The explanation: Here, I1MAX=IZMIN+ILMAX.

IZMIN =0.5mA, I1MAX =(V1MAX-VZ )/RS . PUTTING the values we get , I1MAX =24.2mA.

So, 24.2-0.5=23.7mA.
