The figure shows a DC voltage regulator circuit, with a Zener diode of breakdown voltage=6V. If the unregulated input voltage varies between 10 V to 16 V, then what is the maximum Zener current?
2.5 mA
1.5 mA
7.5 mA
3.5 mA
Zener diode -
It can operate continuously without being damaged in the region of reverse biased
- wherein
1) It acts as voltage regulator
2) In forward biasing it act as ordinary diode .
When the battery voltage is 16 V, the maximum current will be obtained
Option 1)
2.5 mA
Option 2)
1.5 mA
Option 3)
7.5 mA
Option 4)
3.5 mA
