In the given circuit the current through Zener Diode is close to.......\(mA\)
- A \(0\)
- B \(6.7\)
- C \(4\)
- D \(6\)
Answer & Solution
Correct Answer
(A) \(0\)
Step-by-step Solution
Detailed explanation
\(12-500\left(2 i_{1}+i_{2}\right)-10=0\) \(\Rightarrow \quad 2 i_{1}+i_{2}=\frac{2}{500}=\frac{1}{250}\) \(< i_1\) when zenor has break down. \(\mathrm{So}, \mathrm{i}_{2}=0\)
