In a Zener diode, the reverse bias voltage is \(3 \mathbf{V}\) and the width of the depletion region is \(300 \stackrel{\circ}{\mathrm{~A}}\), the electric field intensity will be \(\qquad\) \(\frac{\mathrm{V}}{\mathrm{cm}}\).
- A \(10^{4}\)
- B \(10^{6}\)
- C \(10^{8}\)
- D \(10^{-2}\)
Answer & Solution
Correct Answer
(B) \(10^{6}\)
Step-by-step Solution
Detailed explanation
B.\(10^{6}\)
\(\mathrm{E}=\frac{\mathrm{V}}{d}\)
\[
\begin{aligned}
=\frac{3}{300 \times 10^{-8}} \\
=10^{6} \frac{\mathrm{~V}}{\mathrm{~cm}}
\end{aligned}
\]
\(\mathrm{E}=\frac{\mathrm{V}}{d}\)
\[
\begin{aligned}
=\frac{3}{300 \times 10^{-8}} \\
=10^{6} \frac{\mathrm{~V}}{\mathrm{~cm}}
\end{aligned}
\]
