MCQ

For the forward biased diode characteristics shown in the figure, the dynamic resistance at ${I}_{{D}}=3 \,{mA}$ will be $.....\,\Omega$

✓
$25$
B
$30$
C
$35$
D
$40$

✓

Answer

Correct option: A.

$25$

a
$R_{d}=\frac{d V}{d i}=\frac{1}{\frac{d i}{d v}}=\frac{1}{\frac{(5-1) \times 10^{-3}}{0.75-0.65}}$

$\frac{100}{4}=25\, \Omega$
