  • Question 1
    4 / -1

    In the case of constants α and β of a transistor

  • Question 2
    4 / -1

    If l1, l2, l3 are the lengths of the emitter, base and collector of a transistor, then

  • Question 3
    4 / -1

    In an NPN transistor circuit, the collector current is 10 mA. If 90% of the electrons emitted reach the collector, the emitter current (iE) and base current (iB ) are given by

  • Question 4
    4 / -1

    Least doped region in a transistor

  • Question 5
    4 / -1

    The transistors provide good power amplification when they are used in

  • Question 6
    4 / -1

    The transfer ratio of a transistor is 50. The input resistance of the transistor when used in the common-emitter configuration is 1 k Ω. The peak value for an A.C input voltage of 0.01 V of collector current is

  • Question 7
    4 / -1

    For a transistor the parameter β = 99. The value of the parameter a is

  • Question 8
    4 / -1

    In a PNP transistor the base is the N-region. Its width relative to the P-region is

  • Question 9
    4 / -1

    A common emitter amplifier is designed with NPN transistor (α = 0.99). The input impedance is 1 k Ω and load is 10 k Ω. The voltage gain will be
