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

  • question_answer
    The plate resistance of a triode is 2.5 ´ 104 W and mutual conductance is 2 ´ 10?3 mho. What will be the value of amplification factor                                                        [RPET 2002]

    A)            50  

    B)            1.25 ´ 107

    C)            75  

    D)            2.25 ´ 107

    Correct Answer: A

    Solution :

               \[\mu ={{r}_{p}}\times {{g}_{m}}=2.5\times {{10}^{4}}\times 2\times {{10}^{-3}}\]=50.
