Question 76 of 209

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

Show answer and solution

Answer: 9


i=604000Ai=\dfrac{60}{4000}A
i1=305000A{i}_{1}=\dfrac{30}{5000}A
i−i1=604000−305000=91000Ai-{i}_{1}=\dfrac{60}{4000}-\dfrac{30}{5000}=\dfrac{9}{1000}A
current from zener diode

i2=i−i1=9mA{i}_{2}=i-{i}_{1}=9mA
