In the circuit shown below, maximum Zener diode current will be _____ $mA$ .

In the circuit shown below, maximum Zener diode current will be _____ mA .

Correct answer

0

Step-by-step solution

Current through load resistor is ${I}_{L} = \dfrac{60V}{10000Ω} = 0 . 006A$ and current through $4000Ω$ resistor is $I = \dfrac{\left(120 - 60\right)V}{4000Ω} = 0 . 015A$
Thus, maximum current through Zener diode is ${I}_{Z} = I - {I}_{L}$
$= 0 . 015 - 0 . 006 = 0 . 009A = 9mA$
