  • Question 1
    4 / -1

    The amplification produced by a triode is due to the action of

  • Question 2
    4 / -1

    In an experiment, the saturation in the plate current in a diode is observed at 240 V. But a student still wants to increase the plate current. It can be done, if

  • Question 3
    4 / -1

    In a triode amplifier, the value of maximum gain is equal to

  • Question 4
    4 / -1

    For a given triode µ = 20. The load resistance is 1.5 times the anode resistance. The maximum gain will be

  • Question 5
    4 / -1

    The voltage gain of a triode depends upon

  • Question 6
    4 / -1

    In a triode valve

  • Question 7
    4 / -1

    The amplification factor of a triode valve is 15. If the grid voltage is changed by 0.3 volt the change in plate voltage in order to keep the plate current constant (in volt) is

  • Question 8
    4 / -1

  • Question 9
    4 / -1

    A triode has a mutual conductance of 2 × 10–3 mho and an amplification factor of 50. The anode is connected through a resistance of 25 × 103 ohms to a 250 volts supply. The voltage gain of this amplifier is

  • Question 10
    4 / -1

    14 × 1015 electrons reach the anode per second. If the power consumed is 448 milliwatts, then the plate (anode) voltage is
