  • question_answer
    A transistor has \[\beta =40.\]A change in base current of \[100\,\mu A,\] produces change in collector current

    A)  \[40\times 100\] microampere

    B)  \[(100-40)\] microampere

    C)  \[(100+40)\] microampere

    D)  \[100/40\]microampere

    Correct Answer: A

    Solution :

    [a] \[\beta =\frac{\Delta {{I}_{C}}}{\Delta {{I}_{B}}}\] or  \[\Delta {{I}_{C}}=\beta \Delta {{I}_{B}}=40\times 100\,\mu A\]
