Q60JEE Main 2022 · 29 JUL · SHIFT 1Easy

P-N Junction Diode

If the potential barrier across a p-n junction is $0.6\text{ V}$ . Then the electric field intensity, in the depletion region having the width of $6 \times 10^{-6}\text{ m}$ , will be __________ $\times 10^{5}\text{ N/C}$ .

Numerical answer type. Work it out, then open the answer.

Show answer and solution

Answer: 1

$E = \dfrac{V}{d}$
$E = \dfrac{0.6}{6 \times 10^{-6}} = 1 \times 10^{5}\ \text{N/C}$
So the answer is $1$ (i.e. $1 \times 10^{5}\ \text{N/C}$ ).
