    The resistance of a germanium junction diode whose \[V-I\] is shown in figure is \[({{V}_{k}}=0.3V)\]

    A)            5 kW

    B)            0.2 kW

    C)            2.3 kW

    D)            \[\left( \frac{10}{2.3} \right)k\Omega \]

    Correct Answer: B

    Solution :

                       \[{{V}_{k}}\]= knee voltage = 0.3 V            \[\therefore \]Resistance \[=\frac{\Delta V}{\Delta i}=\frac{(2.3-0.3)}{(10-0)\times {{10}^{-3}}}=200\Omega =0.2k\Omega \]
