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
