C. Remain constant
D. Cannot be determined

2. (TCO 1) As the AC input voltage increases at the transformer primary, the secondary voltage will ______. (Points : 4)

A. Decrease
B. Increase
C. Remain constant
D. The output will go to zero.

3. (TCO 1) As the load resistance increases, ______. (Points : 4)
