    The minimum potential difference between the base and emitter required to switch a silicon transistor ON is approximately?

    A)  1 V                                        

    B)  3 V

    C)  5 V                        

    D)         4.2 V

    Correct Answer: A

    Solution :

    To switch on the transistor, the emitter-base junction of a transistor is forward biased while collector-base junction is reverse biased. The cut-off voltage for silicon is\[1\,\,V\], so to switch on a silicon transistor a potential difference of\[1\,\,V\]approximately is required between the base and emitter.
