1) The resistance of germanium junction diode whose V-I is shown in figure is$ (V_{k}=0.3V)$ A) 5$k\Omega$ B) 0.2$k\Omega$ C) 2.3$k\Omega$ D) $(\frac{10}{2.3})k\Omega$ Answer: Option BExplanation:Resistance , $R=\frac{\triangle V}{\triangle I}=\frac{2.3-0.3}{10 \times 10^{-3}}$ $R= \frac{2}{10} \times 10^{3}=0.2 \times 10^{3} \Omega=0.2 k \Omega$
