R=(Δ V/Δ I)=(2.3 - 0.3/10 × 10- 3) R=(2/10)× 103 R=0.2× 103 Ω =0.2 kΩ

Q. The resistance of a germanium junction diode, whose $V - I$ characteristics is shown in the figure, will be $(v_{k} = 0.3 V) .$

$5 k Ω$

$0.2 k Ω$

$2.3 k Ω$

$(\frac{10}{2.3}) k Ω$

$R = \frac{Δ V}{Δ I} = \frac{2.3 - 0.3}{10 \times 1 0 ^{- 3}}$
$R = \frac{2}{10} \times 1 0^{3}$
$R = 0.2 \times 1 0^{3} Ω$
$= 0.2 k Ω$
