Semiconductor D...

TIME LEFT -
  • Question 1
    4 / -1

    Assertion : The resistivity of a semi-conductor decreases with temperature
    Reason : At higher temperature more co-valent bond breaks

  • Question 2
    4 / -1

    Assertion : NAND (or NOR) gates are called digital building blocks
    Reason : The different combination of NAND (or NOR) gates can produce all the basic or complicated gates.

  • Question 3
    4 / -1

    Assertion : The colour of light emitted by depends on its forward bias.
    Reason : The forward biasing of PN junction diode will increase the width of depletion layer

  • Question 4
    4 / -1

    Assertion : The ionization energy of isolated phosphorous is very large
    Reason : The ionization energy of phosphorous in lattice is very small

  • Question 5
    4 / -1

    Assertion : Mostly transistor are used in common emitter configuration
    Reason : Common emitter configuration provide more current gain and small voltage gain

  • Question 6
    4 / -1

    Assertion : A transistor amplifier circuit in common emitter configuration has low input impednce
    Reason : Base - emitter junction is forward biased

  • Question 7
    4 / -1

    Which of the following logic gate will have output 1 ?

  • Question 8
    4 / -1

    The symbol respresents :

  • Question 9
    4 / -1

    The logic circuit shown in the figure, is the equivalent diagram of which logic gate ?

  • Question 10
    4 / -1

    For the given circuit of ideal P.N junction diode which is correct ?
