In the figure there is a DC voltage regulator circuit, with a Zener breakdown voltage = 6 V . If the unregulated input voltage varies between 10 V to 16 V , then what is the maximum Zener current?

Question

In the figure there is a DC voltage regulator circuit, with a Zener breakdown voltage = 6 V . If the unregulated input voltage varies between 10 V to 16 V , then what is the maximum Zener current?, 1 . 5 mA, 7 . 5 mA, 3 . 5 mA, 2 . 5 mA

MARKS App · Accepted Answer

i 1 = 6 4 = 1 . 5 mA Maximum current will be obtained for battery voltage 16 V i = 16 - 6 2 = 5 mA i 2 ( max ) = 5 - 1 . 5 = 3 . 5 mA
