The zener diode has a \(V _{ z }=30\, V\). The current passing through the diode for the following circuit is \(\ldots \ldots \ldots \,mA.\)
- A \(3\)
- B \(9\)
- C \(12\)
- D \(18\)
Answer & Solution
Correct Answer
(B) \(9\)
Step-by-step Solution
Detailed explanation
\(i =\frac{60}{4000} \,A\) \(i _{1}=\frac{30}{5000} \,A\) \(i - i _{1}=\frac{60}{4000}-\frac{30}{5000}=\frac{9}{1000}\, A\) current from zener diode \(i _{z}= i - i _{1}=9\, m A\)
