The zener diode has a ${V}_{z} = 30V$ . The current passing through the diode for the following circuit is___ $mA .$

The zener diode has a V _ z = 30V . The current passing through the diode for the following circuit is___ mA .

Correct answer

0

Step-by-step solution

The zener diode has a V _ z = 30V . The current passing through the diode for the following circuit is___ mA .

$i = \dfrac{60}{4000}A$

${i}_{1} = \dfrac{30}{5000}A$

$i - {i}_{1} = \dfrac{60}{4000} - \dfrac{30}{5000} = \dfrac{9}{1000}A$

current from zener diode

${i}_{2} = i - {i}_{1} = 9mA$
