  1. (TCO 1) The DC or average voltage will do what when adding an additional capacitor in parallel? (Points : 4)
    Increase
    Decrease
    Remain constant
    Cannot be determined
    2. (TCO 1) As the AC input voltage increases at the transformer primary, the secondary voltage will ______. (Points : 4)
    decrease
    increase
    remain constant
    The output will go to zero.
    3. (TCO 1) As the load resistance increases, ______. (Points : 4)
    the ripple voltage will increase
    the DC voltage will increase and the ripple voltage will decrease
    the DC voltage will increase and the ripple voltage will increase
    the DC voltage will decrease and the ripple voltage will decrease
    the capacitor opposes a change in voltage so both the DC and the ripple will decrease
    4. (TCO 2) If the coupling capacitor shorts out, ______. (Points : 4)
    the DC voltages will be changed
    the AC gain will change
    the circuit will work better at higher frequencies
    5. (TCO 2) If the BJT is saturated, ______. (Points : 4)
    Vce = 0
    Ic = 0
    Beta = Ic/Ib
    Alpha = Ie/Ic
    6. (TCO 2) For the waveforms given below, Ch A is on top and Ch B is on bottom. Calculate the gain and phase difference.
    (Points : 4)
    7m and 180 degrees or out of phase
    145 and 0 degrees or in phase
    145V and out of phase
    120 and out of phase
    145 and 180 degrees or out of phase
