Resolved Question:

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
