JEE Main & Advanced Physics Semiconducting Devices Question Bank Valve Electronics (Diode and Triode)

  • question_answer
    The slope of plate characteristic of a vacuum diode is \[2\times {{10}^{-2}}\,mA/V.\] The plate resistance of diode will be [RPMT 1999]

    A)            50 W                                        

    B)            50 kW

    C)            500 kW                                    

    D)            500 kW

    Correct Answer: B

    Solution :

               \[{{r}_{p}}=\frac{1}{\text{slope}}=\frac{1}{2\times {{10}^{-2}}\times {{10}^{-3}}}=50k\Omega \].
