  • question_answer
    For a vacuum diode, slope of a characteristics curve is \[2\times {{10}^{-2}}\,mA{{V}^{-1}},\] then plate resistance of diode is:

    A)  50 \[\Omega \]                               

    B)         50 \[\text{k}\Omega \]

    C)  500 \[\text{k}\Omega \]             

    D)         500\[\Omega \]

    Correct Answer: B

    Solution :

    Plate resistance \[{{r}_{p}}=\frac{1}{\begin{align}   & 2\times {{10}^{-2}}\times {{10}^{3}} \\  & =50k\Omega  \\ \end{align}}\]
