In figure E19.12a, two light bulbs are connected in a loop that surrounds a solenoid connected to a source of AC current. In this case, both bulbs glow brightly. Now suppose that we connect various points in this circuit with a thick (low-resistance) copper wire, as shown in figures E19.12b through E19.12d. Which bulbs glow in each case?
-C.

A) Bulb $A$ glows but bulb $B$ goes out.
B) Bulb B glows but bulb $A$ goes out.
C) Both bulbs continue to glow.
D) Both bulbs go out.
E) One needs more information to answer.
