a. The current has a constant value and is directed from the top of the inductor toward the bottom of the inductor.
b. The current is increasing and is directed from the top of the inductor toward the bottom of the inductor.
c. The current is decreasing and is directed from the top of the inductor toward the bottom of the inductor.
d. The current is increasing and is directed from the bottom of the inductor toward the top of the inductor.
e. The current may be increasing and directed from the top toward the bottom or decreasing and directed from the bottom toward the top of the inductor. c. e.
