In the following circuit, the reading of the ammeter will be : (Take Zener breakdown voltage \(=4 \mathrm{~V})\)

- A 24 mA
- B 80 mA
- C 10 mA
- D 60 mA
Answer & Solution
Correct Answer
(C) 10 mA
Step-by-step Solution
Detailed explanation
\(\mathrm{V}_1=\frac{400}{100+400} \times 12 \mathrm{~V}=\frac{4}{5} \times 12=\frac{48}{5} \mathrm{~V}\) here, \(\mathrm{V}_1 \gt \mathrm{V}_{\mathrm{z}},\left(\mathrm{V}_{\mathrm{z}}=\right.\) Zener Voltage \()\) So, Zener breakdown will be take place. So, voltage across…
